I get that Ronaldo was something special before, always arrogant, but special, i also get that he actually did "okay" last season, but when he is on the pitch for this Manchester, it is not like he gets anything to work with, the whole team keeps serving him 100% chances, he has a few in every game, some time it has been just insane to see how much Bruno TRIES to make him look good.
He is done, he is still in good shape, but he has lost his edge/speed and maybe even hunger.
I get that people in general are still not happy about where Man Utd. is, but they are on a upwards curve, they play better ball, and they are a bitter team without Ronaldo than with, so he just needs to be somewhere else.
