My personal opinion on the whole Scharner rant is that it’s old news that’s been dug up from weeks or maybe months ago.
I’m not convinced that it’s something that’s happened recently although I could be wrong.
There’s an interview with Scharner on Latics Player regarding the Villa game and his own personal game playing in the back 4 and bringing the ball out from the back starting attacks. He seemed happy with the role and said there’s still room for improvement, was laughing away and being his usual self, didn’t seem unhappy in the slightest.
My personal view is that this ‘rant’ with Roberto happened a while ago (if at all) and the media/papers have only just got hold of it to print in the papers.
As for the signings, I think Roberto will be thinking along the lines of 1 or 2 players maybe leaving or if we pick up any injuries in the next couple of games. That wouldn’t be an ideal situation and obviously he would need cover/replacements for the departed or injured players.
