I am guessing this is the image you're referring to. I was wondering how come about those bruises too when I first saw it last night on ESPN. Could this image really be truth?
I understand Pep Guardiola is very passionate and dedicated coach that always want the best for his club but I think he is taking it too far right now. With what I can see on this image , I think he is allowing emotions to control him, if the team is not doing well it is better tp look for a solution to help the team bounce back again, all these drama won't change anything. It is very funny to see Pep Guardiola in this manner, he feels only Manchester City deserve the best and other teams don't deserve to be the best. He needs to learn to accept the outcome of football, and try his best to make things work when things are not going far and this is how football works.
