Shad Forsythe’s wife posted a picture of him at AC Milan a few days ago and I wanted to see if any denials followed, but so far there has been silence.

Ivan Gazidis reportedly wants to bring Shad Forsythe to AC Milan as their Head of Performance. It is a story that started with a picture and has developed over the past few days.
So far, at the time of writing, nobody connected with either Forsythe or AC Milan have denied the rumours.
It is possible that Forsythe is feeling marginalised after the arrival of Darren Burgess in 2017, however, that’s two years ago. If he was unhappy you’d have to think he would have found a new job by now.
No, as Occam’s Razor says, the most obvious answer is usually the correct one.
Ivan Gazidis is trying to poach Arsenal staff.
Forsythe arrived at Arsenal in 2014.
