I'd personally go with a standard 4-3-3. I think we risk overcomplicating things and losing our way a bit if we start alternating to 3-4-3s or 3-4-2-1s.
I just think we need to get our mentality and our pressing back, the way it was against Spurs, and the formation will be fine.
If we can come flying out at them, and put a massive effort in with and without the ball for the first 20 minutes, the crowd will get right on board and then we can take the momentum from there. International break after this, so we need to put one big push in and leave everything on the pitch.
Much as I'm a staunch defender of his, I do think there's a reasonable argument to leave Barkley on the bench now for a game or two, take him out of the limelight and let him watch from the sidelines for a bit.
I also think we've become very imbalanced in the way we seek to attack. Everything is coming down the right again, and the left side is largely anonymous. So for that reason I would move Bolasie out to the left.
So I'd go:
Coleman Jags Williams Holgate
Gana Cleverley Barry
High energy, high pressing, loads of effort. Encourage the players to shoot often, and get the Friday night crowd into the game early on and take it from there.
