His problems began with the City game for me. In that game, for me, he did quite well tactically, using Davies, Holgate, Rooney and DCL to give the defence the opportunity to ease the pressure and move higher up the pitch on particularly City's left hand side. I thought we showed defensive intensity in this game too, I accept we could have been more positive given the game scenario, but we also defended City's formidable attack line fairly well, perhaps better than anyone else has this season (viz. the RS).
But since, we've shown zero tactical nous, and I think he might have used a different lineup in every single game. The players seem to understand their roles within the team less and less as each game goes by. Now most of them are on international duty again, and Koeman is apparently on holiday (again), how are the players supposed to figure out their position and match instructions within our nebulous / existentially challenged 'tactical system'?
I think Koeman has made a mistake not being decisive and sticking with a system that was halfway working - or at least made sense in theory. And now, though I do hope this isn't the case, it seems as if he just can't really be arsed fixing it, to me it's like he's just trying anything and everything hoping to stumble on a sub-optimal selection that gets the odd three points to ease the pressure, on him. It feels like hopeless trial and error to me, his tactical choices. I know he didn't get the players in that he wanted, and that makes it very difficult to know our best lineup, but for 6 million a year or whatever he earns I expect someone to at least be able to decide on a team selection and set of tactics and stick to it. Even if forming a plan B is difficult, I expect something resembling a plan A for 6 million pounds a year.
