If he is found guilty of drink driving there is a slight possibility he may get sent to prison as its his second time.
In a weird way that may actually be what he needs, he needs some sort of wake up call, he made a number of mistakes at the Albion and instead of that being a deterrent, somebody then pays £12m, gives him millions in a signing fee and a £70k a week contract, its like he was being rewarded despite being an idiot.
A spell inside, realise thats where his life is at now, may just hit home some truths and give him a reality check because whatever he is doing now isnt working. All the 'god is great' 'i love my mum' mottos are just words, he needs to reassess his life, who his friends are, etc and try and rebuild his career, even if he isnt found guilty you have to question why he keeps ending up in these situations, its disrespectful nowadays to be out the night before a game, let alone possibly be on the beers.
Even if he does get sent down, if he showed genuine remorse, turned his life around, then some club will give him a contract. Without opening a can of worms, the Lee Hughes situation shows clubs will offer deals because they have scored goals previously and thats what everyone wants.
