I hope he does move. Young british talent and arsenal just doesn't work out. I'm struggling to think of one british player who have improved under Wenger.
Walcott - showed promise early on, never upped his level or improved his consistency. Cannot get a game for club or even in the England squad.
Ramsey - Amazing for wales, in and out of the arsenal team. Shows glimpses, but is a bit static.
Chambers - Can barely get a game for Arsenal, one to be continuously loaned out
Jenkinson - See Chambers
Wilshire - Started amazing, looked a world beater. Now getting ridiculed in the u23's
The Ox - Lots of ability, played in various positions, cant nail down a spot. Hasn't really kicked on
Welbeck - Is he better now than he was at UTD? Nope
Gibbs - Solid left back, cant get a game ahead of Monreal who isn't the best around
I know injuries come into play in some scenarios, especially Wilshire/Welbeck, and I know I'm generalising with the home grown thing, as you could say majority of foreign signings don't improve under wenger also, but I look at the talent the above have and I'm baffled by how poor they have all become under Wenger.
The Ox specifically, I hope he moves on and makes a go of it somewhere else. Would be the best thing for him and his progression.
Look at Chalobah, loan after loan, finally gets his move and in the England squad. Got to be playing regularly
