I'm not sure mate, it's all smoke and mirrors clearly, but you can say USM are a significant sponsor, and by virtue of that, the Chairman (of whatever his official title is) - Usmanov, has a material interest in being involved in the selection of the clubs manager.
There has also been talk that the stadium lenders and I mean book lenders here, took an interest in who was being appointed and leaned on Moshiri to avoid taking what was considered a "gamble" appointment such that Benitez was considered "safe".
I did think the presence of Usmanov's nephew was a bit odd yesterday though. Is he still connected with the women's team? Either way, it can be "explained" if anyone came calling and looking for an explanation. The fact that it can be, means that it won't.
