That's not reassuring at all. As drastic as the decision might be, I think it's the only course of action. I will see how he does today (he's debuting in half an hour), but given his foul tendency with his previous team, hope is little. Since he won't play any key role in my team in the near future, as he was bought mainly to train, I may wait some weeks to sell him, at least till he gets expensive enough to compensate the investment. But it's truly a shame, as I said before, I was meaning to buy his teammate and I got confused when bidding.
Thanks for your comment.
