WATCH: Dries Mertens finishes off Wolfsburg with a goal to give Napoli a 2-0 lead

Napoli were already coasting to the finish line after Jose Callejon's goal, but Dries Mertens didn't want to let his buddy have all the fun against Wolfsburg.

That's how you stay committed to the play until the finish. It was a tremendous effort by Mertens to get on the end of that and stay with the play until something good happened. His reaction to the rebound was perfect, and it ended any faint, remote, tiny shred of hope that Wolfsburg had left in this Europa League tie.
