Manchester United boss Sir Alex Ferguson is confident Carlos Tevez knows he must fight for his place.

"When you have a squad of players, everyone must get their share," said Ferguson.

"The important thing is Carlos makes a great contribution.

"He has started a few games already. By the end of the season, you will see how many he has participated in - and that contribution will have been very important to us.

"No one has played all the games. They have all had minutes on the clock; some have had time on the bench, and sometimes they have not been involved at all.

"That is exactly what happens with squad rotation in the modern game."
