Barcelona midfielder Xavi has claimed that last night's 2-2 draw with AC Milan was "unfair".
The European champions led 2-1 until the last minute when Thiago Silva headed in to hand travelling Milan a share of the spoils.
"What happened on Tuesday is pure bad luck, totally unfair," the 31-year-old told Barcelona TV.
Barcelona's next match is a home La Liga fixture against Osasuna.
