According to twitter it’s basically done.
Some interesting comments from some Gooners. Hope they are right, they seem to rate him -
Good luck to the gills he's a solid looking player hopefully he does well for you
Left footed CB, been hovering around our first team for 2 seasons quite highly thought of
I’m glad for him. I think his natural position is defensive midfield. He’s similar to Luiz
Yeah or 6ft 4 (or5) I think either one, quality signing tho a lot of championship teams wanted him as well, and he’s been on our bench so done bits
