Napoli coach Carlo Ancelotti was left frustrated after their 1-1 draw with Genoa.

Stefano Sturaro's dismissal handed Napoli the advantage - which they failed to exploit.

“I don't think the players were distracted, because we haven't talked about Arsenal at all. We knew the difficulties we could run into in Empoli, although the difficulties we ran into tonight were a little more unexpected," Ancelotti responded ahead of their Europa League quarterfinal with Arsenal.

“We're defending badly at the moment, even when it was 11 against 10, and that means we cannot control the game. If you control the game, you don't allow counter-attacks, you don't let the opposition to turn and run at you.

“It's an alarm bell, certainly, because if we play like this in London, then we're in trouble. It is unusual to see Napoli doing that, so we have four days to focus back on the basics, because these are basics we're getting wrong."
