According to Ferguson during an interview with Skysports “Wayne is going through a period like all strikers do, he is not scoring,”
“He has missed bits of games and been off with tonsillitis, and Wayne is the type of player who can’t miss games because of the frame he has got.”
Regarding the use of Rooney within the diamond formation, Ferguson added: “I am happy with that part of his game.
Rooney scored 34 goals in the 2009/10 season as a lone striker but has taken a back seat since the arrival of Van Persie from Arsenal in the summer.
Ferguson is impressed with the impact that the former Arsenal striker has made and said: “Without doubt Robin is an up-front player.
“He has experience and now our players are starting to realise how good he is. We are getting more aware of the runs he is making and the movement he has up front. Hopefully that understanding gets better.”
The Premier League leaders head to Reading today and the manager is not concerned that their previous fixtures have not been attacking classics.
“I don’t think the form has been that bad to be honest,” the Scot added. “But when you are manager of this club, you have to go through that analysis about Manchester United not being as good as they used to be.
“We are still top of the league so we must be doing something right.”
