'I didn't know who to call': Ernesto Valverde dropped unreal punchline before losing to Barca

"I wish someone could tell me how to beat Barcelona, but since they haven't lost [this season], I couldn't find anyone to contact," Ernesto Valverde told the media minutes before facing Barcelona.

Hours later, the former Barca boss lost to his former club despite putting up a fight.

At times, it seemed like Bilbao were the better side – but this is when Marc-Andre ter Stegen came to the rescue.

Barcelona remain unbeaten in all competitions this season. Xavi's side have won 7 La Liga games and shared the spoils in 3, also winning two Champions League clashes.
