I 100% agree mate. I honestly think he thought it would be less hassle, not too demanding, club with a decent past but a job like a Stoke or West Ham where he doubles his wedge.
It was the man utd home game for me mate. For an hour we were absolutely woeful, brings on Calvert Lewin, suddenly the fans are like "at last he's trying something different, raises the rest of the players and we suddenly start playing football, aggressive, effort and looking fitter culminating in Baines scoring a 90 minute penalty.
The Arsenal game mimicked the Utd game except we got in front and then had some unreal luck at the end but it was like a light switch where the players finally believed in themselves and in the method of Koeman and maybe even Koeman started to believe in the players and his method.
