Valencia coach Rino Gattuso says the fans will be key against Barcelona today.

Gattuso expects a heaving Mestalla against the Blaugrana.

He said, "I like to keep our style, but let's see how Barcelona play and the players they have. We have to respect them, but the style and mentality of my team is not going to change.

"Mestalla always has a great atmosphere. I think that tomorrow we will have 45,000 people in the stadium and that has to give us strength. However, in all the games that we've played at Mestalla, including the friendly, the supporters have been great. I'm very proud of the support from the fans and I hope that the game we have tomorrow will make the fans proud too.

"I like to talk about my own team. I know that we are seeing two different versions of FC Barcelona. In LaLiga they are scoring a lot of goals, conceding few, and playing incredible football, but in Europe it's different. I think they have very talented young players and it will be a difficult match."
