Ever Banega put the hosts ahead at the Mestalla before Lionel Messi scored in his 12th Liga game in a row, this time from the penalty spot, to make it 1-1, and Roura believes the Blaugrana lacked freshness after their Copa del Rey semi-final with Real Madrid in midweek.
He told reporters after the match: "There is no doubt that we come into this after a very tough match in Madrid.
“Our showing in the first half cost us, and Valencia had a great intensity in the second, playing higher up the pitch, from a physical standpoint.
“As always, we came with the intention of winning, but what happened was we found it difficult at the Mestalla and, in the end, a draw is fair enough.
"We lacked intensity in the first half. We lacked depth in the second half; we had three or four very clear chances. Overall, we did not have the freshness of other games, but it's understandable. "
Tito Vilanova’s assistant also heralded goalkeeper Victor Valdes for his display on the night, with the Camp Nou shot-stopper having received a lot of criticism since making his decision not to sign a new contract.
Roura said: "We are delighted with Victor, we have always said he is the best goalkeeper we can have.
“Today he played at a very high level, and we will continue helping and assisting in any way we can while he is still with us."
