Morale
Podolski has turned into an almost Emmanuel Eboue cult figure and fan favourite despite his lack of game time during his last season at the Gunners (which may go some way to explaining why so many fans are heartbroken with his exit).
But his ability to befriend any in the squad and become almost the court jests of the Arsenal side will surely be missed as he goes to Italy as will the morale boosting presence he brought to the training ground.
