The issue is Rose has been awful for a very long time .. in hindsight you could argue he was only very good for a couple of seasons. It's not a position of strength, yes it would be easier to get back to form if you play more games, but you have no devine right to that, and the fact that we were willing to play people out of position instead of him should have been a reflection point for him, not just "a slap in the face as he put it"
The interesting piece is, Toby, Eriksen and Rose all were affected by Poch in the end, loss of form, didn't want to be there, perhaps confidence/self belief, the only one who took the opportunity to reset themselves was Toby (and even then, think it took quite a few games for his performance to return to par)
It really was a clusterfudge with the injuries .. how we got out of that season with 6th after that start, the form from previous year and injury pile up ..
