Valencia came back from a goal down to lead 2-1, but conceded a goal in the dying second of the game.
Emery told Marca: “If we play like this, we will win more than we draw.”
“In Getafe we played poorly, but we deserved to beat Atletico, although we have now dropped four points at the Mestalla. Banega was substituted because he was exhausted, as well as to shore up the defence.
“The fans were behind the team except for that change and the last minute goal, but their anger comes from the emotion behind the result.
“I will prepare for Genoa without nerves, because I have seen more positive things than negative.”
