So, Jason Ayto (previously at Arsenal, then became sporting director at Brighton) has left his role at Brighton after less than a year in charge.
Edu also on the cusp of leaving Nottingham Forest despite only joining them 18 months ago after leaving Arsenal.
Then you look at some of the previous guys we had. Raul Sanllehi - his contract was not renewed and then went to Inter Miami, where he was sacked after 5 months. Then Vinai Venkatesham, who is now at Spurs. Probably a decent commercial guy, but has zero footballing operational experience and has been getting dog's abuse for Spurs almost going down.
It does beg the question what some of these people were doing at Arsenal and how they were allowed to be at the club for so long.
I think it's no coincidence that the minute Arteta gets a smooth, capable and experienced operator in Berta, we end up winning the league.
