Alex Iwobi and Mohamed Elneny then both had penalty claims waved away by Jon Moss, but the referee who sent Jamie Vardy off for diving kept his cards in his pocket this time.
Foster saved well from Ozil before it was over, but much like Arsenal’s title challenge, the game slowly fizzled out.
So there was no collapse this time. No blown lead and chorus of boos. But it felt like a hollow victory. By the end, the stadium really was half empty.
As for the cake. It looked nice and seemed to have all the right ingredients, but wasn’t about to win any major prizes. Sound familiar?
