Barcelona coach Ernesto Valverde won't be underestimating Villarreal on Sunday.

Barcelona take on Villarreal this weekend in need of a win to keep in touch with LaLiga Santander leaders Sevilla.

"They have caused problems for us before and it will be difficult for us to circulate the ball.

"They can perform well in different systems and they work well on the ball."

When asked about Arthur's condition, Valverde wouldn't give too much away.

"If he's on the squad list he's there to play.

"Otherwise, he won't be there."
