"He was disappointed, I was disappointed. I want him to score four or five goals every game like he did at Luton, but I don't care," said Guardiola post-game.
"He can miss this one and be sad for 10 seconds and miss five more and be sad for 10 seconds more. But after that, erase it and onto the next one.
