Napoli coach Carlo Ancelotti believes Champions League opponents Liverpool are stronger than last season.
The Azzurri host the European champions this week.
“Liverpool have grown because last season gave them so much awareness," Ancelotti said at a Press conference.
“On the other hand, we've also grown because we've added more quality to their squad.
“It'll be a hard-fought match as we'll be facing the best team in Europe. We hope to get the same result as last season.
“As for formation, we mustn't distort our identity and idea. We must take inspiration from the good things we've done and the problems we've been faced with.
“We defended very well against them last season, and the defensive aspect is very important in games like these.
“I expect a team capable of defending when necessary, attacking when the opportunity arises and keeping the ball when needed. We'll need the perfect game."
