Young's been out for ages. Garner can't be moved to the wing given the lack of CMs (and Doucoure will be exposed against Villa's midfield if he's dropped back so needs to be as forward as possible).
I thought it might just be a back 5 again but Dyche will probably be scared from Wolves.
I actually think Gomes might get a start in this. Dyche was happy to put him in v Man. City so don't see why Villa would be any different and they play at a slower tempo generally so Gomes will get some time on the ball and that could be enough to get a key pass or two through to the forwards.
Mind you he's had some shockers against Villa in the past. That August 2019 game he was completely hopeless at Villa Park.
