Manchester City's Erling Haaland was awarded a penalty against Chelsea because Marc Cucurella failed to let go of the striker despite the Norwegian holding the full-back in the build-up.
City took the lead in the 25th minute on Sunday after referee Anthony Taylor awarded the spot kick much to the anger of the home players and fans.
Many cited the fact Haaland had hold of Cucurella's shirt as a reason why the foul should not have been given. But the full-back's insistence to keep hold of the striker was his downfall according to former Premier League referee Dermot Gallagher on Sky Sports' Ref Watch.
Explaining why the decision was given, he said: "You see it sideways and you can’t unsee it. They are both grabbing at each other, Cucurella doesn’t let go and hauls him to the ground and you cannot unsee it.
