I have MC on my team, who trains really fast and he's got the highest level of all my midfielders. But his ratings are abysmal this season - 5 or even 4 each and every game. He used to play well at the beginning, but it's looks like he's got a form crisis. I've had a similiar case in the past and I had to sell one of my favourite MC players. So maybe it's a common affliction.
