The keeper apologised after the goalkeeping errors in the defeat to Real Madrid in May, but when he published a professionally produced video on social media which showed him enjoying himself in California, it sent the wrong message to some of his team-mates.

Fellow players and staff felt it was disrespectful as it suggested that the 25-year-old didn't care about the crucial errors he made in the box.
The video on his Instagram didn't sit well with fans either and after suffering a barrage of abuse, Karius removed it.
And according to the Daily Mail, there was no going back from it in the dressing room.
When Alisson arrived, it then not only sent Karius further down the pecking order but it saw him shunned further within the club.

The shot-stopper's move to Turkey came in the wake of his Champions League final errors, but Liverpool stated that wasn't the reason for him leaving.
Jurgen Klopp and his players jumped to the keeper's defence over his fumbling in the final against Real Madrid.
But when the German goalie uploaded videos of himself in LA they soon changed their tune.
And then the club did a U-turn on their decision to keep him, noting that he was surplus to requirements.
But, Klopp did take the opportunity to praise the German shot-stopper for his efforts during his time at Anfield when he left.
When Liverpool splashed the cash on Alisson they were expecting someone of quality and they've certainly got their money's worth.
Karius has since sought refuge in Turkey with Besiktas.
