You're a loon. Of course a professional footballer who wants to continue a career talks favourably of himself. The suggestion that he should do otherwise is entirely unreasonable. It's utter utter lunacy to suggest that anyone would talk down their value.
Who's mentioned wanting him to talk down his value? I just posted the exact opposite view to that. I know you're a fan and struggle to see this objectively. But there is a range between honest assessment and confidence/delusion/cockiness/wishful thinking etc. In my view VB crossed the acceptable threshold in his AA interview last night. Came across as sounding entitled to my mind.
Anyway, you're incredibly wrong. What he said on radio last night is for public consumption and his own ego only. His continuing career has nothing to do with what he says on radio but rather the frank and honest conversations he has at the club with the coaching group. Don't be such an idiot.
