So what's Dyche doing here that has you arsed, then?
Doing as poor as he did at Burnley, clearly showing that the 7th will never happen again and was a fluke, buying players he doesn't even play for arbitrary reasons, and finishing in the lower parts of the table and claiming improvement, while the football gets worse as time goes on.
We can be revisionist all you want and Koeman was/is a giant fat turd, but he got a deflated team that was midtable and on a downward spiral back to Europe while losing the best defender we had and getting Ashley Williams in return. We "improved" on the team by shuffling off permacrocked, cyclist's enemy, Gibson and getting Schneiderlin and Gueye in, in his first season, and Stekelenburg as a stop gap at GK, then getting Pickford, who is a permanent starter and one of the top reasons we're not down. We also did get Keane then though, has to be said, even though his stock was quite higher than it is now. He did get more or less the best out of that team in his first year, we had a poor run around this time which ultimately cost us 6th, but we were the genuine best of the rest together with United and had quite a few winning streaks.
He then went on a spree of getting central attacking mids for some reason, we lost Lukaku and replaced him with no one really, we didn't kick on, and he was rightly binned when the results suffered. That might also be karma for removing Prince Niasse's locker access though, we can't be sure. Or chatting bubbles about Barcelona, etc. etc.
