Per Mertesacker is probably one of Mesut Ozil's biggest fans and he'll surely be annoyed by the latest stunt pulled by Arsenal detractors.
YouTube channel CheekySport are behind the footage that sees a fan ask Mertesacker to donate to a 'missing person' fund for Ozil.
Poking fun at the Germany international midfielder's dip in form, supporters took a donation bucket around the Emirates Stadium as they trolled the former Real Madrid star.
Ozil hasn't scored for the Gunners since December and drew criticism from former Manchester United defender Gary Neville after his display in the 2-2 draw with Manchester City at the weekend.
One particular incident saw the playmaker race through one-on-one with Willy Caballero but Ozil wasted the opportunity as the ball ran loose and out for a goalkick after the Argentine closed him down.
Watch Mertesacker unwittingly donating to the Ozil 'missing person' fund in the video above!
