Manager Sir Alex Ferguson might call on both midfielders for the friendly against his son Darren's Peterborough at London Road - Hargreaves is on the mend following a knee injury while Anderson has been away on international duty with Brazil.

Peterborough boss Ferguson told the Evening Telegraph: "Owen is training this week and if he comes through unscathed he could be here on Saturday. There's a chance we could get Anderson and (Ole Gunnar) Solskjaer as well. I'll know for sure later in the week but if players like that turn out, it should be a great occasion."

Peterborough have sold more than 9,000 tickets for the match even though United are due to face Chelsea in the Community Shield the following day.
