The slowed down footage clearly shows the ball deflected off Llorente’s arm before hitting his thigh and ended up in the net.
AS’s resident referee Iturralde González commented: ”It hits his hand first then his hip and the UEFA instructions are clear: you can't score if it hits your hand, even if it’s involuntary. It doesn't matter if the elbow is tight to the body. If it happens to a defender it's not a penalty, but if it's an attacker it has to be disallowed. Rossetti has told the UEFA referees.”
He added: "Irrati (the VAR) - the number one VAR official - advises Çakir because he's seen a hand. When Çakir comes back from seeing the images he tells the players 'I didn't see anything. It hit his thigh.' They didn't play him the view from behind where you can see it hits the elbow. The error from the VAR is not showing the two key images. Why? The question is getting it right, not how long it takes."
AS’s resident ref's conclusion: "Manchester City are out because the VAR wasn't used properly".

My conclusion: People in the VAR room had the luxury of having multiple angles and clearly saw that the ball hit the arm of Llorente but refused to show that angle because there was an agenda already.
