If anyone is actually interested in the reasons it’s not worked out for him and can put aside the job he did at Sunderland then here’s some of them I can see:
1) The football has been horrible. Doesn’t matter whether it wasn’t when he was at Sunderland. It has been here.
2) Following on from point 1, we’ve lost interest. We don’t threaten wins over the top teams (even at home the best we can hope for is a 0-0 Draw) and have been comfortably outplayed when we’ve lost.
3) This is his biggest club job and his opportunity to show it’s not all about him and he’s failed. Throws the players under the bus when results are negative and takes all the plaudits when they’re positive.
4) Disrespected the fans on numerous occasions. Batted away criticism as “15 fans on the internet” and laughed at fans when asked about any pressure.
5) We want to be better than 7th and/or win Silverware. Allardyce’s entire career suggests he isn’t capable of that. Don’t forget we only actually wanted him for six months. He played a blinder to make it an 18 month contract.
6) This is a minor and petty one. He keeps taking credit for a 4-0 win when he wasn’t even in charge against West Ham.
7) This is a big one. Serious question marks over what he can do with our young talents. Davies desperately needs to improve on the ball which won’t happen under Sam. Lookman was shipped out to Leipzig (Sam wanted him to go to Derby) and has tore it up whilst Sam preferred the dismal Bolasie. Calvert-Lewin and Holgate haven’t seen much game time either.
Worth saying that he wasn’t actually at your club for very long and you could easily have been fed up quickly with him yourselves had he stayed. As that’s what happened with O’Neill, Di Canio, Payet and Advocaat before him.
