5) Harry Kane – England
The prolific forward who is essentially the driving force behind Tottenham’s incredible finish last season, unfortunately, fell short of replicating that zing for England's Euro venture.
Prior to the beginning of Euro 2016, England manager Roy Hodgson was widely hailed for his theoretically perfect team. All departments and positions seemed to be well provided for and Kane was, of course, deemed indispensable for the side.
However, that did not seem to be the case as Kane ended up contributing nothing at all to England's otherwise decent performance. Former England striker and current MOTD pundit Alan Shearer harshly criticised Roy Hodgson's decision to not substitute Kane for Jamie Vardy in the second half.
Given the disappointment that England has consistently faced on the international level in the recent past, an early exit is perhaps the last thing that the team needs. Kane needs to improve and he needs to do so fast.
