#1 Harry Kane - England
It was really difficult to choose between Harry Kane and Lukaku, but the fact that he captains the English team and his miss from a couple yards being a huge error sees him top this unlikely list.
The 24-year old Tottenham striker had been in stellar form for his club and had stepped up his game even further when the World Cup campaign started.
While the loss to Croatia wasn't his fault alone, his lack of involvement in the final third and the failure to inspire his team into scoring an equaliser, let alone a winner was his fault as a captain and he became increasingly absent in what was his worst game of the tournament by some distance.
When Kane got his best chance in the 30th minute against Croatia, his first shot was saved by goalkeeper Danijel Subasic. The ball rebounded almost out of play, then sat up for Kane to take another shot from less than two metres.
The ball hit the post, ricocheted off Subasic and somehow looped off to safety. An offside was called for the preceding play, so it wouldn't have counted anyway.
Sadly Kane would not get another opportunity with the ball at his feet, and Croatia would never let England get so close again, with the Croatian midfield dominating possession and frequently intercepting play.
While the manager's tactics for the game is also to blame for England's loss, it doesn't mask the fact that Harry Kane could have done much better. If it is any consolation, he may still take home the Golden Boot.
