"I feel blessed that we have players like John O'Shea, who has stepped in to play out of his skin," Fergie has said.
"John has thrived on playing regularly and I'm sure that if I asked him to play at centre-forward he would get us a goal.
"It's great to have such adaptable players and it's one of our strengths as we enter the last lap of the title race.
"The attitude of the players has been marvellous, especially when it comes to the business of being left out - there have been no dummies flying out of the pram.
"I hate telling a player that, although he has perhaps just delivered a top-class performance, I will not be using him in the next match.
"It's not nice, but it helps that the players understand."
