Valencia coach Unai Emery admitted he was unhappy with his side's 2-1 defeat to AZ Alkmaar in their Europa League quarter-final first leg in Holland, claiming his side deserved to win.
AZ scored late in each half through Brett Holman and Maarten Martens to win a match their opponents had dominated for long periods.
"I think we deserved the victory and the team now has many more positives than negatives," said Emery, whose side went into the game on the back of consecutive Primera Division defeats.
"But the end result leaves us unsatisfied."
Mehmet Topal levelled for Valencia early in the second half and they had a succession of chances to take the lead, but they could not take them and were undone by Martens' winner.
"We were always in a position to win," Emery added. "AZ Alkmaar's goals penalised us far beyond what we deserved.
"The result is bad, but hopeful. Now we have to be optimistic and continue on this path, creating more chances than our opponents."
