Manchester United manager Sir Alex Ferguson has admitted that little progress has been made in talks to complete the permanent signing of striker Carlos Tevez.
The 24-year-old Argentina international finishes a two-year loan spell with the Red Devils in the summer, with negotiations to seal a deal seemingly having hit an impasse for the time being.
Ferguson commented: "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."
Meanwhile, Ferguson is confident that veteran right-back Gary Neville will be offered a new deal, with his current contract running out at the end of the season.
He added: "I am sure there will be another contract because Gary has been back to his best.
"He is looking really good now and the experience he has is so important to us."
