Sergi Busquets says Barcelona will learn from their thrashing of Celta Vigo.

Celta stunned Barca 4-1 last night.

"After a result like that, the team feels bad," said Busquets.

"Even though we do think that we lost by a much bigger margin than we deserved … We were better than them in the first half. We were more intense. But they scored goals at key moments."
