Owen Hargreaves could be sensationally amongst the Manchester United substitutes for tomorrow's clash with Chelsea.

Although it appears John O'Shea is further forward on the comeback trail, the fact Hargreaves is not part of United's European squad and therefore unavailable for Wednesday's quarter-final second-leg against former club Bayern Munich, lends weight to the belief manager Sir Alex Ferguson will have the 29-year-old on the bench against Chelsea.

"John O'Shea and Owen Hargreaves have trained very well with the first team," said Ferguson.

"They are not far away and I may use one of them as substitute tomorrow and the other on Wednesday.

"John O'Shea in particular has done a lot of work. The boy has come on terrifically well in the last two or three weeks.

"If I include one tomorrow and one on Wednesday it will give them the confidence that they are back.

"That is what they need."
