Barcelona coach Ernesto Valverde admits he may ring the changes for their clash with Athletic Bilbao.

Barca meet Athletic having earned just one point from the past two games.

"We will see if we make some adjustments," he said.

"That doesn't mean that we will change the whole approach, when we look at the team we know we are a side with quality players and I don't think the system is so important.

"We need to deal with the game tomorrow knowing that it will have characteristics which are different to those we have faced up to now."
