Tottenham Hotspur's Dele Alli was hit on the back of the head by what appeared to be a plastic bottle during his side's 2-0 win over Arsenal in the League Cup quarter-finals on Wednesday. The midfielder helped put his team ahead with a superb pass for scorer Son Heung-min in the first half, then netted a beautiful goal of his own, running in and calmly chipping the ball over Arsenal keeper Petr Cech. Minutes later Alli was hit on the head as Arsenal were about to take a throw-in. The player, who did not appear hurt, turned to the crowd and used his hands to gesture the 2-0 scoreline to them. "It made the goal a little bit sweeter," he told Sky Sports.
