Banana skin game for sure. Kenilworth Road has the 19th largest pitch in the PL (Craven cottage being the smallest). Having watched some of their highlights, incl. that Brighton game - the home team seems to use the small pitch well with their pressing and physicality.
Just off the eye test it seems they play with a bit more intensity than Fulham, so we just have to be on it from minute 1 to 90, not give them much of the ball, press their defenders high (they're a bit error prone) and be clinical with our set pieces especially (seem to concede a lot off corners and FKs, incl. against us at OT). Would avoid just taking shots outside the box and focus on getting balls into the area as well, Kaminski is a good GK.
Maybe we could do with an extra man in midfield this game to counter their usual 3-4-3: Start with Case, Mainoo, Mount (if fit)/Mctominay and Bruno in a midfield diamond to bully them a little bit and make it tough for them to play through us? We can always push Bruno to the right or change a midfielder for Rashford later on if it looks like we're comfortable. Could do without Rashford for this game personally - it just seems like whoever dominates midfield wins this game, if we put a couple past them early like Chelsea/Sheffield did, we can just manage the game and finish it off comfortably.
They're not a super tough team, just a tricky one and have spent enough time in the PL now for us to analyse how they set up and play. Our guys need to be up for a bit of a physical contest this Sunday, which shouldn't be an issue for them given we don't play in Europe.
