It's hard a surprise Barkley has issues with alcohol. Was strongly rumoured during his Everton days that he was a party boy. Clip of him with Lundstram last summer when he was clearly off his head, it's summer time fair enough, but wasn't exactly a huge surprise that he was dealing with a "personal issue" soon after. Likely that's where his first stint with us went off the rails with Grealish and his shin injury that didn't heal for ages
Fair play to him admitting that he's addressing the issue and it's impacted his career. Emery clearly rates him and I'm very surprised he has put him back in as a 10 recently.
