You don't need to wait for the window to open to start talking to clubs and players about transfers.
Pep said two weeks or so ago that work is well under way in respect of new additions.
We are being patient with our new players because they are young and inexperienced. They make mistakes among a good number of good plays but we make allowances as we see them get better by learning from their mistakes. Shouldn't we treat Pep the same way? He's dropped some clangers on formation and selection but generally has corrected them and imho is getting better. Shouldn't we cut him some more alack?
