Manchester United manager Sir Alex Ferguson has said that he will rotate his squad ahead of their busy upcoming schedule.

The Scot was forced to play Michael Carrick as a centre-back as United came from two goals down to win 3-2 against Braga at Old Trafford on Tuesday in the Champions League.

Javier Hernandez netted a brace against the Portuguese side, and Ferguson admitted that the strikers is just one area where he could move things around.

"[Javier Hernandez] is improving all the time. He trains magnificently and he has great enthusiasm," said Ferguson. "I must say he has got me thinking. I have got him, Wayne Rooney, Robin van Persie and Danny Welbeck, and I don't know what to do with them.

"We have to look at the big picture – Rio [Ferdinand, rested this evening] with his age and a big game against Chelsea on Sunday. Then we play Chelsea again midweek [in the League Cup] and Arsenal again on the Saturday.

"We have a massive programme and it is important to utilise the squad we have. We have got injuries and putting Michael Carrick [at centre-back] is not the best but we had to do it."

The Red Devils have won all three of their games in Group H so far this season.
