Sarri said, "In the first half we were in trouble because we were tired, physically and mentally,' he said. 'In the second half they lowered their intensity and we went in control of the match. We were lucky of course because we scored after two minutes and after the first goal, probably we improved mentally.
"We were able to play very well for 30, 35 minutes but in the first half we were in trouble, tired, more mentally than physically I think - it's not easy to play after 60 hours.
"In the past after a match away in the Europa League, we won only one match, so it's not easy. As you can see, in the last month, not only for us, but for every team."
