If you think it's nonsense about his drinking you're very naive. Do you think he's supping tea in nightclubs and parties? He had a drink problem at Villa when he crashed his Range Rover when too pissed to walk properly, never mind drive. He's been caught by paparazze several times since staggering out of clubs in the early hours whilst he should have been at home in bed.
The club know full well he has a drink problem but they're not going broadcast it are they because they want to sell him to the highest bidder. It was reported he was the last to leave at De Bruyne's leaving party, no surprise there. Maybe why Pep left him out of the squad against Fulham.
