Bailly will probably play some of the remaining League games now due to missing the Europa League Final. Not quite sure if we'll see three at the back, but this is a nothing game for us now so hopefully Jose can rest who needs to be rested (Namely Valencia, Pogba, Herrera, Mkhitaryan, and Rashford. Blind, Darmian, and Lingard to some extent, as well). Three at the back is probably the only way to leave out Lingard, Mkhitaryan and Rashford, and I'd like to see Borthwick-Jackson brought back in at Left Back, but Jose might have to pick from the reserve players carefully as they play Spurs on Monday as well.
I'd absolutely love to spoil the party and beat them in their last game at WHL, but resting the first team is more important and this is one of the few times where I'm not too bothered if we get beat. Hopefully it isn't by 3+ goals though, even when playing poorly and resting players we've only conceded more than two goals in a game twice this season (Watford 3-1, Chelsea 4-0).

Maybe we'll see some other young players like Ro-Shaun Williams, Poole, Riley, and Willock make one of the squads over the next three games. I do believe that Jose should play the team he has in mind for the Ajax game against Southampton though, just to keep them sharp - then of course, try to rest basically his entire 18 for the Palace game at the end of the domestic season. Players like Smalling and Jones need the games, and Fellaini will probably need an hour in a League game due to the suspension.
Think Spurs will take this, but not a collapse from us no matter what kind of team we see. 2-1 or 3-1 to them, it is their only saving grace this season now, beating United. They're an exciting young team doing well on a lower budget, but if they don't keep the squad together and win something soon, no one will remember the team that came close a couple of times but ultimately weren't good enough. If we win the Europa League, I'd say we've had a better season than every team in the Premier League other than Chelsea (assuming they do the double).
