Barcelona boss Xavi highlighted Athletic’s intensity as key to their victory over the Catalans in the last 16 of the Copa del Rey on Thursday.
The hosts won 3-2 after extra-time with captain Iker Munian striking the winner from the penalty spot after Barca had twice come from behind.
It’s another blow for Xavi and his men and the coach spoke about where it had all gone wrong for his team after the match.
“They beat us because of their intensity,” Xavi said.
“We didn’t control the game. We were not comfortable in the game, so congratulations to Athletic because they showed unbelievable intensity.
