Sevilla won 2-0, hit the woodwork twice and had a goal narrowly ruled offside.
The dominance was evident in the statistics, with 10 shots on goal to zero, and 13 corners to three.
"I too am disappointed, but I have to say we deserved to lose. At this moment, Sevilla are a better team, they played better and we have to accept their superiority," the coach told Sky Sport Italia.
“We did all we could, but it was difficult to play against a team that right now is playing better. It's easy right now to seek explanations for this moment."
He added, “I'd make the same choices again. The same. The team won almost every game in Serie A lately, we were doing well with this system and I had no reason to change.
“If I'd changed the system for this match, it would not have been a balanced approach. It's difficult to accept, but we have to accept without excuses that we lost to a team that simply played better."
