Barcelona legend Xavi admits they were outclassed by PSG in their Champions League thrashing.

Barca are reeling after their 4-0 first-leg defeat.

"In terms of intensity, tempo of play, tactically, physically and mentally," Xavi explained to L'Equipe. "They were on top.

"Barcelona didn't have any chances. [Kevin] Trapp wasn't bothered at all.

"PSG were more aggressive than Barcelona, they rhythm of play was better and this was the difference, because in terms of the quality of players the two teams are more or less at the same level."
