Sir Alex Ferguson wants Gary Neville, Park Ji-sung and Carlos Tevez to receive new contracts at Manchester United - but admits the situation with the Argentinean's permanent deal is unclear.
Tevez's two-year loan to United is due to expire in the summer, with the striker having consistently declared his desire to remain at Old Trafford.
But reports of talks re-opening between the 24-year-old's agent Kia Joorabchian and United chief executive David Gill are news to Ferguson, although he did confirm the club have attempted to instigate negotiations aimed at bringing forward a self-imposed deadline of next May.
Ferguson said: "I have no idea about Tevez.
"The contract is due to be the end of the season anyway but obviously we tried to bring it forward and we will keep trying to do that.
"But it is difficult with agents sometimes. All the managers signing players this January will experience that."
Ferguson also hopes both Neville and Park will stay at the club and believes new contracts will be offered to the pair.
Regarding Neville, whose contract expires this summer, he said: "I have not spoken to David (Gill) about it but I am sure there will be another contract because Gary has been back to his best.
"He is looking really good now and he did a crucial job for us when we brought him on against Middlesbrough last Monday.
"The experience he has is so important to us."
Park recently claimed no-one from United had approached him about a contract that expires in 18 months but Ferguson believes the former PSV Eindhoven player will get a new deal when the time is right.
"It is not on the radar screen but he will be offered a contract," said Ferguson.
"Ji has been fantastic for us and is one of our most consistent players."
