Roura admits they were feeling the after-effects of last week's Copa El Clasico against Real Madrid.
"Valencia pressure you a lot and they don't let you play.
"Their intensity made it difficult for us to play our game and it was hard for us to get close to their area.
"Perhaps we didn't create a lot of chances and we weren't as fresh as we have been in the past. We came here with the intention of winning the three points but it's always difficult to win at Valencia. I think the draw, in general terms, is fair.
"We're coming off a very tough match away to Madrid and that, from a physical standpoint, always wears you down."
