I don't think so. I think it's been Usmanov's cash but it's dried up as recent attention in media and parliament etc exposed thst he was present at interviews and wider knowledge he's still involved means there's an immediate stop to this. Hence why they need some of that cash to pay off Lampard and probably other immediate debts. Moshiri probably hasn't put a penny in. He's not that wealthy in football terms. It won't surprise me if we're completely for sale this week.
Ultimately, Bill has bought these people in to serve himself and in turn they have all literally destroyed us. It's all on him for bringing this darkness to our club and Moshiri is in fact a fraud.
