Manchester United are confident Carlos Tevez will be in a position to sign a long-term contract once Argentina's Copa America campaign concludes at the weekend.

Tevez is at the centre of a messy transfer saga involving United, West Ham, the Premier League and his long-time advisor Kia Joorabchian.

A deal, virtually identical to the one which saw Tevez's fellow countryman Javier Mascherano move from West Ham to Liverpool in January, is in place with United, with the 23-year-old only now requiring to pass a medical and sign before officially becoming a £30m Red Devil.

The problem is who United actually pay the cash to, with the Premier League continuing to insist West Ham should profit as they hold Tevez's registration.

Joorabchian counters this, insisting he still owns a controlling right in the striker.

With allegations and accusations flying about on all sides - and the validity of the Premier League's crucial decision to let Tevez play in the last three matches of West Ham's successful survival fight on the line -- a resolution appears impossible without either legal action or the involvement of world governing body FIFA.

But sources close to United are hopeful that a compromise will have been reached by the end of the week which will allow Tevez to fly in from South America early next week to complete his dream move.
