Villarreal confirmed their place in the last 16 of the Europa League following a 2-1 aggregate victory over Napoli on Thursday, following a 1-1 draw at San Paolo.
Marek Hamsik provided the hosts with hope of qualification when he struck a fine volley from the edge of the area inside 20 minutes, showing exquisite technique to find the bottom corner after the Villarreal defence failed to clear sufficiently.
