Bringing this in here to not derail the transfer thread further.
I dont believe its so black and white (i hate the amount of topics on here that are painted as such) to suggest people would have an idea in their heads on when they would feel we should change manager again.
I was very much behind Martinez and was willing to allow a lot of context and factors in to explain how it all went wrong, but knew all along that despite him earning the right to have a poor 2nd season there was no way he should survive a weak 3rd.
I personally dont want to be in the summer of 2019 with Koeman having signed an extension, having done no better than say 6th and no trophies, and people are still arguing reasons for giving him more time.
For this season the first thing I want to see is a clear gameplan, some intelligence in attack and for us to win a few of our big games. If that looks good and we just fall short of improving on 7th/cup win then there would be a clear enough step up from first to second season to justify the 3rd. Personally though if we have another just ok season, I'd prefer get somebody else in next summer.
