"He has a finger injury, but we don't think that it's a problem that will affect his career as a player, neither tomorrow nor on Wednesday," Solari said during a press conference on the eve of Saturday's game.
"He's looked good in training and he's in a good mood. We're happy that he's with us," the Argentine coach added.
Solari praised the French player for his performance this season as well as his commitment to the Spanish club.
"Karim is our reference in the attacking line. He has had a great year at both the personal and sporting level," Solari added.
