CB: Per Mertesacker (£10 million) – A last minute panic buy from Werder Bremen as Arsenal looked to plug their leaky defence once and for all. Mertesacker did quite the opposite in fact, he made it significantly worse. With the turning circle of an oil tanker and running around like Bambi on ice, the German looked hopelessly out of place in England’s top flight and spent the end of the season out injured much to the delight of the Gunners’ fans.
