From the moment Glasner announced he would be leaving there was moaning on this forum about not getting his replacement lined up. The general (negative) expectation was that the club would bumble around all summer before settling for a compromise appointment a week or so before the season started, leaving the new man with insufficient time to impart his ideas to the players.
In fact the total opposite happened, but the irony is that Sage arriving for duty nice and early surely makes very little difference in the circumstances. Half the players came back late from the stupid, overly long world cup. The squad isn't remotely finalised even now because the geniuses who run the game have the transfer window overlapping the actual games (so most squads are in unhappy flux at this time), and even the manager has no idea what players he's going to be working with apart from that it's probably not the ones he had in summer.
To top it all, by the time the window finally shuts we'll be playing on the Thursday/Sunday schedule for months, carting the players off all around Europe and back. It's generally thought that once a team gets on that treadmill quite a lot of the average week is given over to rest and recovery, and there isn't much time for tactical training. The logic used to be that such work was done in the summer!
The irony seems to be that whilst we got the manager in as early as possible, he might as well have stayed in France until far later for all the good it's done. When exactly is the man supposed to do his work?! He needs his actual squad (and especially his first choice XI) in the building, time to work, and ideally a couple of friendlies to give the XI the chance to practice it all. Instead, he gets the opposite.
Sadly, I can envisage Sage getting the chop by Xmas if grim necessity calls for a Dyche type. If that happens, I imagine Sage will be sat back in France, slightly baffled, and wondering why he was appointed to coach the team if no such opportunity actually ever existed.
