5 January signings Arsenal fans want to forget quickly

Thomas Eisfeld

German prospect Thomas Eisfeld was poached from Borussia Dortmund in January of 2012, and Gooners fans thought they had the next Mario Gotze on their hands.

It wasn’t to be. The German was completely underwhelming at the Emirates and looked well out his depth. Unfortunately Eisfeld was another young player who just couldn’t make it at the club and was sold to Fulham in the summer of 2014.
