Fair comment but how much was spent on the team prior to them winning the League, isn't our bloke worth a few bob he may as well be a pauper.
They took over Leicester in 2010 and they won the league in 2016. Between 2014/15 (when they came back into the league and 2018/19 they had a net transfer spend of £194M.

They appear to have spent around £100M between takeover in 2010 and winning the league in 2016.

Mr Lai's wealth isn't as large as initially thought, I'm sure it's something like £200M, I think he bought the club with the help of other financial backers.
