Goalkeepers are renowned for their eccentric behaviour.
If you wanted to wind up former Arsenal glovesman Jens Lehmann then all you needed to do was step on his toes when lining up for a corner, in the penalty box.
His eventual successor, Wojciech Szczesny, may seem cool and calm off the field but his budding bromance partner and fellow top Gun Jack Wilshere has revealed what makes Szczesny angry… and that is spelling his name wrong!
"It's Szczesny not Sczcesny as he very angrily told me as I arrived!" said Wilshere.
The two stars, who have progressed all the way from the academy into the senior set-up, were pictured at the annual Arsenal Foundation Ball - a "flagship event in the charity's fundraising calendar".
The players have already wrapped up fourth place in the Premier League and remain on course for glory this year as an FA Cup final at Wembley Stadium awaits them against Hull City on Saturday, May 17.
The Foundation Ball may well be a night to remember, as famous chef Raymond Blanc has been brought in to design the menu, while entertainment is provided by Rudimental and the London Essentials. The evening is also hosted by Dara O Briain.
