I actually don't mind him going on the lash, it's literally the only interesting/engaging thing about the whole City treble (hence why everyone is so desperate to focus on it!) and I would’ve absolutely done the same, but at the same time, you just know that if was a certain group of other players doing it, it would very much be being reported in a different way. Hell, even the England players dentist chair debacle from the 90s was treated as a scandal rather than a jolly. He gets away with it 'cos he's a loveable himbo but imagine it was Sterling, or Rashford.
Two or three years back there was a minor hoohah because Lingard posted a few videos on Instagram (?) where himself, Rashford and a few other United academy graduates were clearly on the sauce in a hotel room in America. Bear in mind that there was nothing actually offensive about these videos, they were just drunk.
The way a few people reacted was very strange given that, well, let's just say football fans generally aren't known for being pillars of temperance.
I think there's evidently a racial element to it. It's not that white players aren't ever questioned on their attitude but more that the scope of what is and is not perceived to be acceptable behaviour for non-white players seems narrower than for white ones.
To be clear, I'm not suggesting that the answer is to be tougher on guys like Grealish. Quite the opposite. On the whole, I find him really likeable (irritatingly so, in fact), and am more generally of the opinion that within reason we should leave these guys to enjoy themselves off the pitch however they see fit. The argument I am making is these allowances should also be made for non-white players.
