The Reds had 16 shots in the game, but failed to convert a number of clear cut chances.
He said: "It was a crazy game. To create all those chances and only score one goal feels average.
"What can I say? We created, created and created. Where is the real point for criticism? We tried with all we had. The effort was great.
"We have to be more clinical 100% for sure. The only way to change it is to do it again."
