Barcelona No2 Roura impressed by Valverde's Valencia
The two teams meet tonight.
Roura said: "They've won five of their last seven matches. They're focused, very dangerous on the break and will push us very hard. I don't think they'll play any differently against us, despite the defeat [against Real Madrid] they suffered."
As for Barça's title challenge, he said: "Winning would be a step forward".
