Napoli travel away to face Sparta Prague on Matchday 5 of the Europa League. The Partenopei were successful in defeating Sparta during the first encounter of the group stage, with a 3-1 scoreline.

Rafael Benitez’s men enter the contest in low spirits after throwing away a two-goal lead to Cagliari this past weekend and dropping two points in the process.

But the group will need to refocus immediately, seeing as they face their toughest group-stage opponent in Sparta. Both sides are tied on nine points; Swiss-based side Young Boys trail closely behind the leaders on six points.

There is little room for error for Napoli.

At the very least a draw will surely put Napoli in a good position to progress into the next round. If they do fail to garner any points, they could potentially find themselves in a familiar situation as last year's Champions League campaign—exiting from the group on 12 points.

Here are some key issues and decisions that will shape this Thursday’s Europa League clash.
