Yes, and I believe he has turned down Manchester United in the more recent past.I think he turned down Liverpool previously, which was when TB made him Deputy chairman.
He's done the England National Team/FA and he's been at his boyhood club (Spurs) as well so that's all ticked off. Think the only place we'd lose him to is the Premier League CEO job, but even then he'd have to give up his interests in the Albion which may not be beneficial for him.
As @JetsetJimbo said, his daughter does work in football but he was very clear that he stays out of her way and she's forging her own career. Can't see that having any bearing on any decision for his own future.
