Roma spent the Christmas break in Florida and returned on Thursday, so some suggested they could suffer from jet lag.
“I don’t think jet lag had any influence. We created six or seven chances, more than our opponents, but we did not convert them and they did, so that is football.
“We knew Napoli played on the counter-attack and they managed it straight away with a fast move. In my view they scored some great goals and we have to applaud them.
“Cavani is very quick, certainly quicker than Burdisso and Castan, so we tried not to leave him in that one-on-one situation.”
