Tevez - set to sign permanent United deal.
Carlos Tevez rejected overtures from Real Madrid this summer because he was happy to commit his future to Manchester United.
Tevez will sign a four-year contract with United at some point over the next couple of months now talks over his ownership have been concluded.
The Red Devils have agreed a £33million fee with Tevez's owners, who are no longer MSI, for the Argentina forward.
"Carlos Tevez's economic rights are owned by a third party, based offshore but this is not MSI," confirmed Tevez's long-time advisor Kia Joorabchian.
Tevez's initial arrival at Old Trafford was dragged out almost until the start of last season as the Premier League satisfied themselves over a loan deal for the striker, even though it was almost identical to the one which saw Javier Mascherano leave West Ham for Liverpool.
But the 24-year-old created a hugely favourable impression at United, leaving Sir Alex Ferguson in no doubt he wanted to sign the player permanently.
Now that move is almost complete, although not without some interest from elsewhere.
While there has been no comment from Joorabchian or United, it is believed two clubs approached the South American, one of whom was Real Madrid.
Joorabchian, though, did say: "We will help him accelerate the deal to make sure it goes through.
"Everyone's keen to make sure his future is dealt with in the correct way.
"Manchester United have been fantastic with Carlos - he's very lucky to have them and they are lucky too because he's been very good for them.
"It looks like it should happen - but we don't know the timing, whether it will be a month, two or six.
"But we'll make sure when the time is right everything is done smoothly."
He added on Sky Sports: "He is very happy at United and that's the key. That's all he wants to concentrate on.
"He has been with us since the age of 19 and we will continue to play a big part in his career going forward.
"We want to make sure United get the best out of him. When he gets on the pitch he doesn't stop - that's why he is one of the best players in the world."
United did the Premier League and Champions League double last season - and the Argentinian wants a repeat this year - with the FA Cup to boot.
Joorabchian continued: "He wants to do the Treble - that's his ambition at the moment.
"He had six months at West Ham struggling at the bottom but managed to help them survive - and in his first season at Manchester United he won the double.
"He's won 11 major titles and he's only 24 - but winning the Champions League meant the most to him - he's extremely proud to win that with Manchester United. They are one of the biggest clubs in the world."
Joorabchian also moved to clarify Tevez's position on Cristiano Ronaldo.
Tevez was quoted earlier in the week claiming his United team-mate should be allowed to join Real Madrid if he wishes.
However, Joorabchian explained: "Carlos isn't the type to talk about other players or their futures.
"He said that Cristiano has to make up his own mind and that it's up to him - obviously we want him to stay but if he wants to leave there's nothing we can do.
"That was what he said through his broken English - which is getting much better."
