Sir Alex Ferguson insists he is relaxed with the length of time being taken for Carlos Tevez to sign a permanent contract with Manchester United. The Scottish tactician however 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.

"It is not as if we have been short of negotiations.

"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."
