Fickle - changing frequently, especially as regards one's loyalties or affections.
I'm not dead set on whether Bruce should stay or not and I'm guessing you'd describe me as fickle. The thing is that you'd be right to criticise people who called for Bruce's head based on just one bad performance, but that's not what this is. We've been playing poorly for the majority of 2014 and we have only won 2 games from 17 so far this season. These poor results are not due to a lack of talent however, we have spent about as much in one transfer window as we had in our entire history as a club. Bruce spent £10m on a striker who has looked very poor, signed a player in Ben Arfa who he clearly didn't know how to manage or what to expect from him when everyone else knew exactly what he would give, both good and bad. The team are completely devoid of confidence and a huge role of being a manager is making sure that doesn't happen, or fixing it when it does.
Tactics have been poor in many games, switching between the back 4 and 3 and changing personnel too much to get a solid starting 11 (although I accept that injuries have played some part in this). We have dropped off when leading which has lead to us conceding and only taking the 1 point from the game rather than the vital 3. Players are not committing from midfield enough to get ahead of the strikers and cause defenses problems, our strikers often seem extremely isolated and we've turned to route one football which does not suit us at all.
The fact that he isn't doing well at the moment doesn't take anything away from what he did with our promotion and first season up. He will always be a great City manager for what he did there. But we must now move on from that and focus on what is happening in the now. Can he turn our season around? Does he have the managerial ability to change things with the players he has, and if not should he be trusted with yet more money in the transfer window? These questions don't have simple answers and call me a "poodle" if you like but if I was the chairman I would be having serious thoughts about who was in charge of my investment, and whether they were still the right man for the job.
