Dele was an absolute winner even when he was a younger player with us. He hated losing and would leave everything out there, whilst making key contributions on the pitch.
I think you really have to go back and look at the entire chronology of Dele Alli. The stuff with his mum and dad, the MK-Dons foster situation through to the series of soft tissue injuries, and the eventual mental health issues that haunted him. Dele had PTSD from his childhood which included sexual abuse and other horrible things, but still managed to be totally professional in his job. In fact, even when he was injured he worked tirelessly to launch his businesses that still run today. He wasn't out boozing and my guess is that he hates the stuff after having an alcoholic mum. He did like some finer things in life though. Don't recall many different women though. He wasn't a playboy, he just had attractive and intelligent girlfriends from what I remember. The medication addiction was a big problem, and he tried to lose himself in computer games to hide his mental health challenges.
I always remember when Dele was making yet another comeback from a hamstring injury. Roy Keane was having his usual pop at him for not contributing what he used to do in the team. Then Sky put the running stats up and Dele was top. He'd smashed through the 13km mark again, one of only a few players to do it in the PL.
Yes, prime Dele was a leader and winner on the pitch.
