Because the media assassination of his character worked. Whether blues want to admit it or not its affected a lot of our own fans as well unfortunately. Sane gets more leeway despite being the same age... Whilst watching that video there were a number of chances Sterling put on a plate for a team mate and they scuffed it, but they aren't Sterling so they're in the clear. Yeah, Raheem misses a few, but I bet he also gets a lot more chances than everyone else in the team too. He never sulks either, whether its going his way or not. Funny how Pep nearly always starts him, despite all of the projected best 11s at the season start had him on the bench behind Jesus, Bernardo, Sane, Aguero, Alexis, etc.
Notably, Bernardo in his CityTV interview, name dropped Sterling as someone who should have been up for player of the season along the three nominated. A player that has been keeping Bernardo out of the team. Shows you how much his team mates think of him despite the greater football world still being apprehensive.
