A few things arise from all this:
We have had weeks since we sold Lukaku to get a replacement striker, and Koeman has mentioned the need for one in several interviews in recent weeks. At NO POINT did anyone say "we can get one if we sell Ross Barkley" so I do not believe Barkley's about turn fucked up any deal.
I never saw the Moshiri interview but it appears he said something along the lines of Barkley will not feature on the Everton team. Is this not a contradiction of Koeman saying he can still be part of our plans? And who picks the team Koeman or Moshiri? Could this 2nd transfer window fuck-up be the start of a bit of friction between the two? Broken promises, crying for a striker and not getting one? Let's face it Koeman has shown that he shoots from the hip and doesn't take shit, and he only stays the customary two years at places, so a few bad results because of no striker and he could say told you so and fuck off.
With Koeman gone Barkley then signs a new contract, Unsworth plays him as a striker, he dives like fuck every time he gets in the box, we get stacks of penalties, Baines will be top scorer, we finish 7th. Simple.
