Tevez trained with his new team-mates at Carrington after the 23-year old got through his medical this morning.
Manchester United boss Sir Alex Ferguson said: “We are delighted.
“Carlos trained with us this morning and he did very well.
“He was very enthusiastic about the situation, so he will train again tomorrow.
“Then, we have a couple of games on Wednesday; in Belfast and Dunfermline. He will be involved in one of those and play the full game.”
