#2 Theo Walcott
There is no doubt that Theo Walcott's career at Arsenal has been a success, but at 28 years of age, it may be time to move on. Having only made three Premier League appearances this season, it is clear that Walcott no longer holds a place in Wenger's starting XI.
With Alexis Sanchez, Alexandre Lacazette and Mesut Ozil making up Arsenal's formidable attack, Walcott should think about looking for a new club, and he sure won't have a hard time finding one.
He is certainly an asset that many Premier League clubs would love to have, and can easily earn first-team football elsewhere. Similar to teammate Callum Chambers, Walcott currently is not in the fold for the World Cup squad next summer. However, half a season of regular football may be enough to sway the English manager, Gareth Southgate's decision.
At 28-years-old, next year may be the forward's last chance at a World Cup, and he will certainly want to try his best to make it. Unfortunately, sitting on the bench at Arsenal will not help his case.
