According to a Brighton forum Razak has been throwing house parties and has pissed off Poyet who has dropped him. Assulin hasn't played much lately either but for different reasons (slight injury).
This is really disappointing about Razak, it looks like he's well and truly adapted to the English young footballer way of life, him changing nationalities to England from Ivory Coast seems fitting if he's going to act like this.
He has worlds of potential but this sort of thing is what can hurt or ruin a young player. I hope the club try and sort him out as he's a great talent but after a good start at Brighton his bad behaviour is now leading to him playing less which could mean a wasted loan move.
