Well so far this year (could be wrong on this) Kos, Vermaelen, Gibbs, Jack, Chamberlain, Cazorla, Giroud and Podolski have all signed contracts?
Meaning it will be a year or more before the stampede for parity with Theo begins, unless you happen to be Sagna and Arteta.
Given their ages, both are at a big disadvantage.
Unless Wenger really thinks we can do without Theo (and forget the delusion that we'd buy somebody as effective for less than it would cost to keep him) then I don't see the point in getting rid because of a reluctance to pay £100k per week
