Manchester United boss Sir Alex Ferguson insists there's no injury concerns for Edwin van der Sar.
Tomasz Kuszczak played in last night's 2-0 defeat of West Ham and Ferguson explained on MUTV: "Edwin turned 38 today.
"We don't need him to play every game because we have two very capable goalkeepers in Tomasz Kuszczak and Ben Foster.
"Ben being back fit is a big bonus to us because he is an outstanding goalkeeper. I may play him at Celtic Park next week. They will all get their minutes on the clock."
