#2 Alex Oxlade-Chamberlain
Crossing over to the other side of North London, Ox's career has started to have uncanny similarities with that of Walcott – uncertainty over his best position, stunted development due to nagging injury issues, and a relatively long time spent at Arsenal with nothing much to show for it.
Having once made it to England's World Cup squad as a 17-year-old, Walcott's eventual progression (or lack of it) has been a complete disappointment – not a career Ox would be enthusiastic to emulate.
With uncertainty over his future, and two among the best managers in the world (Klopp and Guardiola) vying for him if reports are to be believed, it would be quite surprising if Ox stays at Arsenal beyond the summer. With Wenger's future up in the air as well, it makes sense for Ox to seek a fresh start to his career at this point.
