"I had just one problem with Cristiano, very simple, very basic and it's from a tactical aspect that I noticed, which I brought up in order to improve upon and make him better. And at that moment he didn't take it very well because maybe he thinks he knows everything and the coach cannot help him to develop more."
It could have been a match made in heaven. The best player in the world (if you remove Messi) and the best manager in the world (if you look past Guardiola, Klopp, Ancelotti, Simeone etc.), Sadly, like Ryan Gosling and Emma Stone in La La Land, they could never make it work. Oops, spoiler alert.
