The man who makes Melbourne Victory's midfield tick could make a shock return to rescue the troubled champions' season, which is in danger of imploding.

Skipper Carl Valeri has been training in the gym for several months as he tries to rebuild his fitness after being forced out of the game with an inflammatory condition which affected part of his brain, impairing his balance, co-ordination and his ability to stand.

In recent times he has rejoined his teammates and has been playing in training and practice games, giving rise to hopes that the former Socceroo could make a surprise return for some crucial end of season games.

"I would hope that I might be able to play in some games. I couldn't play a season, but we will have to see," was Valeri's guarded comment.
