Manchester United boss Sir Alex Ferguson has admitted he has a selection dilemma on his hands when it comes to injured midfielders Anderson and Owen Hargreaves.
Ferguson, along with the other 19 Premier League managers, must name a 25-man squad eligible to compete in the first half of the season on August 31.
Nobody outside side of that squad will be able to play league games before the transfer window reopens in January and Ferguson must decide whether to keep places back for Anderson and Hargreaves.
Anderson is currently recovering from a cruciate knee ligament injury, while Hargreaves continues to be troubled by the tendinitis issues which have dogged him for the past two seasons.
"It does give me a problem, but I have just got to wait as long as I can," explained Ferguson.
"I have to make a decision at some point of course and it depends on when I think those players can come back.
"Most of it (the squad) is formulated in my mind, but one or two I have to make decisions on."
