Interesting comment from that article:
The problem with Ravel has and it seems always be is attitude and application.
This stems from his background. He was born and bred on the same council estate in Wythenshawe that i live in now. Ravel's family are known rogues and he was brought up around a rogues gallery of friends and relatives. His mates back then have gone on to be criminals. He is supremely gifted as a footballer but he just cannot get it together mentally.
It was a hard upbringing for him- stories of fights, being caught in friends cars with drugs in, persecuting his ex girlfriend, court dates missed etc.
I knew that if Fergie couldnt get the best out of him then no one would and thus ut has come to pass. He was given so many chances at United, then at West Ham and he just simply cannot keep it together to realise the chances he was given. He has spurned them all.
Regarding the earlier point vs Grealish, I would like to think whatever a persons transgressions may have been in the past, if they make a conscious decision to approach life and career differently they should be offered the same opportunity to do so.
