However, with his side battling on all three fronts at the moment, Ferguson believes that he has a much greater strength in depth.
"We have a stronger squad now When we went to the [Champions League] final, Keane and Scholes were suspended but Henning Berg was the only injury," he told reporters. "I still had to pull in [Jonathan Greening] who had only played once or twice in the first team.
"He got a medal for being on the bench. That gives you an idea of the strength of the squad."
Ferguson's side are currently 12 points clear at the top of the table.
