A video has emerged of a prank handshake with Per Mertesacker before Arsenal’s Champions League tie with Bayern Munich at the Emirates last week that appeared to quite upset the veteran centre-back.
The suited German, sidelined with a knee injury, can be seen strolling towards the home bench in the wake of Steve Bould as the participating players ready themselves on the pitch behind them.
Noticing a young fan recording the moment on his phone and holding out his hand, Mertesacker stopped to shake it.
But the supporter pulls it away in the style of a classic gag.
This seemed to anger the Arsenal defender, who can be seen almost squaring up to the handshake prankster before perhaps thinking better of it.
A series of dirty looks were doled out instead.
