Player was never given a proper chance here. Major failings by the club. They need to have a serious word with themselves, else they're doomed to do the exact same thing all over again. And again...
You have absolutely no knowledge of the situation. No idea what he looked like in training, no idea about his attitude, no idea about how he integrated with the rest of the squad, no idea how he coped with the physicality of football in this country, no idea of his mental state about being in a country thousands of miles from home, and absolutely no idea about why Potter (and / or Percy) have decided this isn't the place for him.
So quite how you can say it is 'major failings by the club', I have no idea (other than that classic thing people do these days of looking at a situation from a position of complete ignorance and immediately making a firm judgement on it).
We've been in the Premier League 5 seasons now. How many other clubs have been relegated out of it in that time? If that situation is us being 'doomed' then I'm good with that.
