Levy isn't just the chairman, he's part owner, the only one who could positionally "sack" him is Lewis who has no day to day interest in the club..Levy doesn’t have blind spots - he’s the longest serving Chairman in the Premier League because he’s extremely good at his job.
You should stick his name into wiki and have a look at the basics of his CV.
Amongst many other business accomplishments, he’s the bloke who squeezed Alan Sugar out of Spurs.
I see a lot of hate thrown at Levy but it’s always because he’s awesome at his job, very difficult to do business with, never suffers an outcome that’s not on his terms (which are always the terms that best manage the interests of Spurs as a business under the circumstances at the time).
I don’t like the guy, but love him or hate him, only someone who knows absolutely nothing about managing a business could accuse him of having a blind spot of any description.
I am thankful to Levy for many reasons but have been getting slow disillusioned with him, undoubtable Covid has messed up his plans.
