Sir Alex Ferguson insists he is not frustrated at the length of time taken for Carlos Tevez to sign a permanent contract with Manchester United.
Having been through such difficulties many times before, not least with former captain Roy Keane and Rio Ferdinand - who was famously heckled during a pre-season tour of Asia four years ago as he delayed signing a lucrative extension - Ferguson remains calm about the situation.
"It doesn't frustrate me," said the United boss. "I have been used to it over the years. You just have to be patient."
Although Tevez has tended to be squeezed out of Ferguson's first-choice side this season following the arrival of £30.75million forward Dimitar Berbatov, Tevez still seems keen to turn his current loan deal into a lengthy stay.
Yet there is no imminent prospect of Tevez signing a contract, despite a series of negotiations between the player's adviser Kia Joorabchian and United chief executive David Gill.
"It is not as if we have been short of negotiations," added Ferguson. "But I think we all know they can take a long time, and this one is just going along.
"David has been talking to his agent, so it is best left to him."
The Argentina striker was making just 12th start when he belted home his four-timer in last Wednesday's Carling Cup win against Blackburn and has now made 21 appearances - more than Rooney or Berbatov - after being introduced as a substitute against Sunderland on Saturday.
Ferguson is confident that should be enough to keep Tevez happy and believes statistics will eventually bear out how important he views the South American within his squad.
"When you have a squad of players, everyone must get their share," said Ferguson. "The important thing is Carlos makes a great contribution."
