When you start losing, everybody starts trying to dissect things. Even at Sunday league level after a defeat, I used to come off the pitch and think - why does he take the free kicks? How come the manager keeps picking him? At this level you can probably magnify that 100 fold. As somebody said earlier, even on this current run, only a couple of performances have been poor (imo) - Fleetwood and Luton. As for bust ups - who knows. However, Doyle who seemed/seems to be the cement both on and off the pitch may have been unsettled by being dropped. You would hope, though, that he is savvy enough to know that at some point he would be dropped and his role in the team/club would change (though it might take him a time to get his head round that).
Performance is a entirely different conversation but for the second time we’ve had a legitimate goal not awarded this season, I’m a believer that things level out over a season so looking forward to claiming at least one of those back.
You don't need to do anything other than look at our goal difference to see what the problem is.
And the problem has existed all season even during our good run.
