How many times has any player ever just sulked and down tools when they haven't got the move they wanted? Ronaldo didn't when Utd didn't allow him to join Real the first year they came in for him, Mascherano didn't when Liverpool blocked his move to Barca when they first came in, Modric didn't when Spurs blocked his move to Chelsea and most recently Suarez didn't when he was denied a move to Arsenal.
Very very rarely does it happen and with a World Cup coming it's almost certain that it won't happen here. Even his agitating now, it's half arsed. There's been no statement from himself there's just been a couple of quotes from a relative which are so obviously not true (re his relationship with Klopp) that you can't take them seriously.
That's quite true really, I suppose that will be the end of the matter then. Coutinho will have to play at his best, and Liverpool won't accept anything. Can it be that absolute? I'm not so sure.
What may be more of a problem is uncertainty over his future rolling into the start of the season (as it is now), it can hang over a team and affect them.
