Barcelona coach Ernesto Valverde says there'll be no underestimating Celta Vigo.

With Juan Carlos Unzue in charge of Celta, Valverde is wary of the Galicians.

"Of course we consider results against Celta," Valverde said. "They have had good results against Barca in recent seasons. We know about the previous games. They don't tell us everything but they show you have to be careful.

"Unzue's their coach, he was at Barca for many years, knows the club inside out... They have a way of playing where they like to dominate the play and sure they will do same tomorrow, with lots of pressure. They're the things we have to worry about."

When Luis Enrique left the club, his assistant at the time, Unzue, was in the running for the job. But the chosen one was Valverde, who is good friends with his Celta counterpart.

He added: "I have known Juan Carlos for a long time, we were together at this club in 1988, so that shows how long known each other and we have always kept in touch.

"He's doing a good job at Celta, he's always enthusiastic about coaching and progressing in his career. I wish him a lot of fortune as he's a hard working person, but hope he doesn't have too much fortune tomorrow!"
