Napoli star Marek Hamsik knows they must beat Villarreal to make progress in the Champions League.

Napoli need three points to guarantee a place in the knockout stages, or at least match Manchester City's result from their game against Bayern Munich.

"We must try to beat Villarreal, whilst seeing what happens between Manchester City and Bayern.

"The Spaniards are struggling in their League and have not recorded any points in the Champions League this year, but they are still a good team, very difficult to deal with. For us it will be a very difficult game, we will have to suffer and struggle until the end of the 90 minutes if we want to succeed."
