Manchester United boss Sir Alex Ferguson has hinted he could rotate his squad more after having a strong bench at his disposal against Arsenal.

With the likes of Michael Carrick and Louis Saha available after injury, The Red Devils manager had five internationals at his disposal for the 2-2 draw at Emirates Stadium.

"We have people fit again," said Ferguson. "I can now alternate our side at times.

"It was the strongest bench I have had this season and that is encouraging for us.

"The lads have done a fantastic job to get us into this position and we can change things now when we need to."

Although it was a good weekend for Chelsea in the title race, Ferguson is predicting more drama to come in the quest for the Premier League crown.

"Both sides are going to be challenging for the title, the draw suits Liverpool and Chelsea," he continued. "And there are going to be lots of twists and turns yet."
