Our issues are that as has been stated, we plan and monitor everything to miniscule detail, we play variations of 4231, 433 possession based football from the top to bottom of our club, all of our recruitment and development of youth strategies are based around implementation of that philosophy at first team level. To see Koeman shoe horning players into 352 for large parts of the season, not using youth, playing players in different positions to those they were carefully recruited to play in (and largely under performing in those positions until restored to their correct positions) playing large parts of the season in a low block playing long ball and publicly undermining our youth players (he said publicly that he was unimpressed with them) has caused concern at board level as it undermines all the other work done by hundreds of people at the club. The owners did not spend tens of millions on infrastructure, employ leagues of analysts and scouts to sift through performance data and videos, target players to suit our system and backroom staff implementing years of development plans for Koeman to play a different system, stick Bertrand at centre back, put Long out on the wing, hand over possession week in week out, sit deep and punt it to Pelle week in week out.
That said, these concerns have to be balanced by the fact that since Christmas we have been 2nd behind Leicester in the form guide. We have beaten our club record Premier League points tally twice in a row under him, beaten every team in the PL during his reign, played some excellent football for sustained periods of time and been very stable defensively throughout, something that I imagine you will be particularly glad to hear at the moment. He is excellent at PR, has a global profile, gives frank interviews and is a personable character, it is quite hard not to like him, I think you will improve a lot under him but that's not hard as you are under performing at the moment. I think he is a good fit for the club and we have a challenge to replace him.
