#5 Harry Kane
This one was (is) debatable, but I refuse to make a twenty-one-year-old player who has no control over the amount paid for him a scapegoat. And, besides I have had enough of 'Sterling' jokes to last me a lifetime.
Harry Kane was supposed to the flag bearer, was touted to be the top-scorer, the pride of London to conquer Europe, instead he took corners with a knuckleball technique. Harry Kane was the top scorer in the premier league with twenty-five goals, but as the tournament went on, he looked more like the striker who was on the bench for a second tier Norwich.
Admittedly, he got nowhere near the service he gets for Tottenham, but he is culpable of doing generally nothing in all the three games he has started. Not, only that, he successfully blocked the position from England's only bright spark in the game against Iceland, Marcus Rashford (in spite of playing only five minutes). So Harry, the Iron throne is all yours.
