Arsenal boss Arsene Wenger has revealed there is an '80 per cent' chance that Gallas will not be fit for the game.

"I hope he will play again soon, but at the moment it does not look too good," Wenger told the club's official website.

"He will play some part before the end of the season, but will he be ready to play against Barcelona? That is another question mark. I would say he is already at 80 per cent out for the first leg.

"But he should play again before the end of the season."
