Watch: Mertens scores, unveils weird 'peeing dog' celebration

When you're having the kind of season Dries Mertens is, you can celebrate any damn way you please.

The Napoli attacker scored his 17th Serie A goal of the season Saturday in the Partenopei's massive clash with Roma, and, after dinking the ball home, decided to get down on all fours and unveil one of the strangest celebrations we're sure to see in 2017.

The little Belgian scored another in the second half to double his side's lead, but there was to be no canine miming this time around.
