This is a sensible post and of course things have been worse, much worse. Comments like the ones you quote are obviously OTT and would be better left unsaid in all honesty but we have played quite a lot of painfully boring football this season, under our new manager (yes we have played well at times, yesterday particularly) and for people to voice their frustrations and concerns about it is as understandable and reasonable a reaction as your suck it up and move onto the next one approach. If everyone did that there would literally be no posts on the reaction thread after a defeat except "Oh well, could be worse, onto the next one" which, let's face it, would be a bit tedious. Football causes emotional highs and lows which are at their most acute during the actual matches and some of the negative stuff is a reflection of the lows just as the "GTFI!!!" stuff reflects the highs. Agree if anyone only ever posts negatively then that's ridiculous.
We are still a work in progress under Puel, clearly there is the possibility of performances like yesterday becoming more regular and if they do it will be difficult for anyone (well, almost anyone!) to find negatives, but if the soporific possession over goals stuff continues then so will, justifiably, the complaints.
