Sir Alex Ferguson has hinted at the summer exits of some senior Manchester United players.
The Scot accepts his side are in need of improbable assistance from neighbours Wigan if they are to pip Chelsea to the Barclays Premier League title. Yet even if United somehow overturn the odds and become the first team to win four consecutive championships, Ferguson feels changes in personnel are inevitable.
"You have to take a decision about where we can improve the team," he told MUTV. "When you are challenging for four trophies it can have a draining effect. You have to be aware of that and spot the moment when it is time to freshen up one or two players."
He added: "It is not a desire to do it but you need to do it because the demands and pressures on players can, over time, be quite exacting."
Ferguson will not torture himself by wondering where it went wrong if Manchester United fail to land a record fourth title on the trot.
Currently a single point adrift of Chelsea, there are a number of obvious points where the gap could have been made up.
"I used to look at every game but you can torture yourself with that," he said
"We lost at Burnley at the start of the season. That was three points and we also missed a penalty. If we had scored that we might have won or at least got a draw that might have made a difference.
"We had a couple of refereeing decision against Chelsea. You could look at all things.
"You can twist and torture yourself but it happens. We get breaks ourselves sometimes."
