Reported rumour is Moshiri is the one leading the negotiation with his agent friend, Kia Joorabchian (who is also Iwobi's agent i think).
Another reported rumour is Benitez didn't want El Ghazi and had turned down 3 times. And there another rumour that there is no bid, just a loan offer. Unsure what's the true story behind it but if the past is any indication with Iwobi, El Ghazi could be Moshiri pushing for the deal.
I think if there is a bid, then I feel the funds are better used elsewhere, like to strengthen our midfield and defense.
