Out of everything his narcissistic ass has done for the cameras, this tops the list. He knew he wasn't on the pitch and wouldn't be getting the spotlight, so he had to make a spectacle of himself on the sidelines..His teammates later said they weren't even listening to him.
Back in 2014, there was a man who was already aware of the irregularities involving Manchester City. That man now runs FIFA. The infamous Gianni Infantino, then UEFA General Secretary, abused his authority, shared confidential documents and, in short, outmanoeuvred the Investigatory Chamber, doing everything in his power to ensure that both Manchester City and PSG would merely receive a fine, avoiding a deeper investigation that could have led to a Champions League ban. All of these details were also revealed through Football Leaks.
Given his actions as UEFA General Secretary and, more recently, as FIFA President, I can only say, in my humble opinion, that Gianni Infantino has become a cancer on football and should have no place in the future of the game.
