Difference between him and Neymar is that Neymar would get suspended deliberately to go partying in Brazil, also he partied when in Barcelona on regular days. I mean, that is the guy who at PSG this season went to Brazil due to a family emergency and was caught going to his dentist and attending a friend's father's bday party while his team mates were playing games.
He traveled to a place not even that far from Barcelona for one day during the two days he was off.
Don't see a comparison.
And well, humble, family man Coutinho faked a back injury for weeks while he played for Brazil to come to Barça last summer too. It's just that Klopp and Liverpool turned out more stubborn than anyone thought.
Ugly side of football every club indulge in nowadays.
