90 mins: The final whistle blows, and Keane's early goal has given Trapattoni his first victory as Ireland boss.
90 mins: Polo gets a shot away from the edge of the area, but it's always travelling wide of the target. Ireland close to victory now.
90 mins: Ireland will have three minutes of added time to negotiate to complete a hard-earned victory here.
89 mins: Keogh is replaced by Wes Hoolahan, who makes his international debut. It'll be a brief one.
88 mins: Keogh hacks clear as Soto tries to bring a bouncing ball under control after a block by McShane.
87 mins: Almero crosse from the left, McShane heads clear. Still Ireland hold on.
86 mins: Polo is the latest Colmbian to try his luck, but his shot never threatens Kiely's goal. Daryl Murphy replaces Doyle as Trapattoni makes his first change with the clock ticking down.
85 mins: Good work from McGeady, tracking back and helping out his full-back O'Shea. Ireland still leading thanks to Keane's early goal.
84 mins: Keane tries to relieve some of the pressure, but he's dispossessed on halfway.
83 mins: All Colombia at the moment, but Ireland are getting bodies behind the ball and making things very hard for the South Americans.
82 mins: The lively Guarin wins a free-kick in the centre-circle.
81 mins: Colombia are pressing hard for an equaliser in these closing minutes. On balance of play, they certainly deserve one.
79 mins: Perea's cross is blocked by a clutch of Ireland players. There are plenty of Colombia fans behind that goal, and they scream for a penalty. Mark Clattenburg keeps his hands behind his back.
78 mins: Guarin strikes it well, but it's always rising over the bar.
77 mins: Perea wins a free-kick for Colombia 30 yards from the Ireland goal and very central. Danger here.
75 mins: Colombia waste the corner, and it's a goal-kick.
74 mins: Miller intercepts Armero's cross from the left, but can't prevent the ball going out for a corner.
73 mins: Keane just fails to pick out the run of Keogh on the right, and Colombia have a goal-kick. Hernandez replaces Torres.
71 mins: Colombia are readying another substitution. No movement yet on the Ireland bench.
70 mins: Delaney stays down after a heavy challenge, while Colombia replace Gonzalez with Armero.
69 mins: Edixon Perea holds the ball up inside the Ireland area and looks to tee up Polo, but McShane is on hand to hack the ball clear.
68 mins: McGeady's corner is cleared back out to him, but he loses the ball as he tries to burst into the area. Appeals from the crowd for a spot-kick as McGeady goes down, but nothing doing. Moreno replaces the injured Perea.
67 mins: Ireland win a corner on the right.
66 mins: Colombia are temporarily down to 10 as Luis Perea trudges off.
65 mins: Colombia make a couple of planned changes: Escobar and Garcia make way for Polo and Soto. There will be another, unplanned one in a moment.
64 mins: Another Mexican wave goes round the ground as Perea receives treatment.
63 mins: Luis Perea is down again, and will not be running it off. He looks in a bit of trouble here.
62 mins: Colombia captain Luis Perea has picked up a knock, but it looks like he can run it off. But the Colombians are preparing to make a couple of changes.
62 mins: It's another superb slick break from Colombia, but Edixon Perea's shot at the end is again well dealt with by Kiely.
61 mins: Doyle's persistence on the right wins a throw for Ireland.
60 mins: Ireland have the ball in midfield, and are again trying to slow the game down and pprevent Colombia launching their speedy counters.
58 mins: The corner comes to nothing and Colombia bring the ball clear.

53 mins: McGeady aims his free-kick to the far post; Ireland's players all move to the near post. Goal-kick.
52 mins: Keane wins a free-kcik wide on the left.
51 mins: The second half hasn't started as explosively as the first, but Ireland will probably be happier to see fewer clear-cut chances than in the first period.
49 mins: Luis Perea halts Keogh's forward run with a fine tackle.
47 mins: Ireland again start the half brightly as Keane looks to find a way to goal.
46 mins: Ireland get the second half under way.
HT: Republic of Ireland 1 Colombia 0
45 mins: The half-time whistle blows, and Ireland are indebted to Keane and Kiely for an interval lead. Colombia have played some classy, intricate football since falling behind early but so far have been unable to get past Kiely.
45 mins: Kiely punches the corner clear by Kiely as the half-time whistle approaches.
45 mins: Somehow Ireland are still ahead. Garcia's shot on the turn is palmed away by Kiely but striaght into the path of Edixon Perea who looks sure to score. But Kiely springs up and makes the block. Colombia have a corner.
44 mins: McGeady looks to find Keane, but misplaces his pass.
43 mins: Torres threads a ball through for Edixon Perea on the edge of the area, but he gets the ball a bit stuck under his feet and can't generate any power in his shot. Easy save for Kiely, but another warning for Ireland.
42 mins: Escobar dinks one over the top, but it's too long for Garcia and runs through to Kiely.
41 mins: McGeady getting more involved now, and his ball from the left almost plays in before breaking to Keogh. His cross is cleared, but it's been better from Ireland in the last couple of minutes.
40 mins: The ball breaks to Delaney 30 yards from goal, but his shot is weak and easily saved.
39 mins: Keane turns and shoots on the edge of the box, but it's blocked.
37 mins: McGeady gets involved for the first time in a while, but his cross from the left is gathered by Zapata. He looks to start a brisk counter-attack but the move breaks down.
36 mins: Colombia aren't afraid to go for goal from distance, but Torres' latest effort sails harmlessly wide.
35 mins: Greedy play from Edixon Perea, shooting from a tight angle when he should have crossed. Kiely makes a simple save at his near post, but Colombia are playing some neat football here.
34 mins: Bustos crosses from the right, but it's easy for Kiely. Colombia, incidentally, have had 10 attempts on goal - half of them on target.
33 mins: Close call for Ireland, as first Miller and then Dunne are forced to make goalline clearances to preserve the 1-0 lead. Ireland living dangerously.
32 mins: Bustos' shot is deflected wide of the Ireland goal for a corner.
31 mins: Chances at both ends as Miller's 20-yard shot is scooped up by Zapata.
30 mins: Good chance for Colombia, as Bustos' cross is met firmly by Escobar. His header is on target, but Kiely dives to his left to beat the ball away.
29 mins: Guarin decides to try his luck from distance, and might wish he hadn't as his shot sails high and wide.
28 mins: Colombia almost get behind the Ireland defence again, but this time Dunne is on hand to clear the danger.
27 mins: Still an entertaining enough game here in London - mainly because both defences are playing like they'd never met their team-mates before.
26 mins: Escobar capitalises on a slip from Delaney to get through on Kiely's goal but shoots tamely straight at the keeper.
25 mins: Glorious chance for Ireland. Colombia try to play offside from the free-kick but make a right mess of it. The ball comes to Delaney completely unmarked on the far post with Keane screaming for the ball in the middle. But Delaney can only slice the ball out for a goal-kick. What a chance.
24 mins: Doyle breaks from midfield and looks set to get his shot away before having his legs taken away by Guarin. Free-kick in a promising position for Ireland.
23 mins: Keane is back defending on the left, and wins a free-kick for his side.
22 mins: Garcia tries to get the better of O'Shea, but doesn't. The Manchester United man plays the ball back to Kiely who clears.
21 mins: The game's been fairly entertaining, but even so there's a Mexican wave going round the ground.
20 mins: The corner is cleared to Sanchez, who slams a shot way over the bar.
19 mins: Delaney concedes a corner, to the anger of the Ireland fans who reckon it should have been a goal-kick.
18 mins: Ireland look to have come through that dodgy period and are now in control again.
17 mins: Keane can't keep the ball in play on the left, and Colombia have a throw.
16 mins: Nice move from Ireland ends with Delaney whipping in a cross from the left, but the ball is sliced into the hands of goalkpeeper Zapata.
15 mins: Torres looks to thread the ball through for Garcia, but Kiely is out smartly to gather.
14 mins: Ireland looking to slow tyhe game down with a spell of midfield possession.
13 mins: Really open game this, and Keane makes space for himself on the edge of the area. He looks to curl one inside the far post but just doesn't get the bend required and Colombia have a goal-kick.
13 mins: Ireland clear the corner, but look a tad uncertain at the back here.
12 mins: Colombia hitting back now, as Edixon Perea gets clear down the left and fires in a low cross that Delaney has to turn behind for a corner.
11 mins: Comical defending from Ireland gives first Edixon Perea and then Garcia clear sights on goal. But neither player can take advantage and, in any case, the offside flag is up.
10 mins: Colombia deal comfortably with the threat from the corner and bring the ball out of defence.
9 mins: Ireland win a second corner.
8 mins: Carlos Sanchez goes for goal from distance, but shoots straight at Dean Kiely who saves comfortably.
7 mins: McShane does brilliantly to make a vital challenge after Edixon Perea looked to have created a shooting chance.
6 mins: Luis Perea concedes a corner as Ireland continue to boss the early stages.
5 mins: Paul McShane's clearance is met by Keogh, who is fouled by Luis Perea.
4 mins: Craven Cottage isn't full for this clash, but the Ireland fans who are here are certainly making themselves heard after that early goal.
3 mins: GOAL - KEANE. Ireland have made a really positive start here, and take an early lead through captain Robbie Keane. He picks up the ball on the edge of the area and his shot on the turn deflects past Zapata and trickles over the line.
2 mins: Keogh nicks the ball away from Colombia and breaks down the right but his cross is too high for both Keane and Doyle.
1 mins: Colombia get us under way at Craven Cottage.
Pre-match: Republic of Ireland boss Giovanni Trapattoni is forced to make a late change for the friendly clash with Colombia with Damien Duff ruled out through illness.
The Newcastle winger has sinusitis so Andy Keogh, whose late equaliser as a substitute secured his side a 1-1 draw with Serbia on Saturday, takes his place.
That enforced change apart, Trapattoni sticks with the side he announced on Tuesday evening, meaning starts for Manchester United defender John O'Shea and Celtic winger Aiden McGeady.
