I do understand that some people were against the Sheikh Jassim bid, but suggestions he doesnt exist are simply idiotic
There are multiple articles from reputable sources in the Financial Times, The Athletic etc going into details about his history in various finance roles over the years - obviously some prefer to live in ignorance rather than actually go and do a bit of research
Regarding the size of any bid, I would wait for an official announcement before analysing anything - just like transfer fees and salaries, half of these numbers are just speculation
