Manchester United boss Sir Alex Ferguson admits injuries could play a major part in deciding which side wins the Premier League this season.
He said: "The run-in is always tough. If you are involved in other tournaments that can play a part.
"If you get a run of injuries that can play a part. It can impact on you.
"It is going to be nip and tuck and points will be dropped. The trick is not to drop as many as your rivals.
"It is not easy but we have the experience and hopefully the strength of our squad this season will mean something and help us."
