That's one way of looking at it, and if this is the case then I have more sympathy than my post shows.I don't think that there are many clearer examples of a young man mentally incapable of the lifestyle of a high profile footballer as Drinkwater.
I sympathise with him for a lot. If your brain is damaged, it doesn't matter who you are or what you do. He's made his mistakes in public and that means he's probably had it very tough.
That said, I can't condone some of the decisions he's made or the attitude to his work. He'd probably agree.
If I were advising him, I'd get out of the game and get some professional help until he's in better shape for dealing with the rest of his life. The alternative isn't pretty.
I can't help but think though that perhaps he is just a bit of an arsehole who didn't know he had it good in spite of many managers giving him the opportunity to turn it around.
Unfortunately, words like complex can mean just that, or are used as an excuse for someone being an arsehole.
Even now, having been to umpteen clubs with numerous managers and more opportunities than perhaps he deserves, he can't see that he has bought it all on himself.
