Manchester United vs Arsenal, team news: Van Gaal reverts to three at the back

Another day, another new formation. It's nice to have a clear philosophy and plan these days, eh?

Yes, Louis van Gaal has picked another system, this time a 3-5-2. In fairness, it's probably largely decided by injury, so it's Smalling, Blackett and McNair at the back with Valencia and Shaw on the flanks. Oddly, Ander Herrera is still only on the bench, so it's - ugh - Michael Carrick and Marouane Fellaini in midfield. Angel di Maria then links all that to Wayne Rooney and Robin van Persie up front.

Confident? Then perhaps you should've saved whatever it is you're on for after the game, you may well need it.

Manchester United starting lineup (3-5-2): David de Gea; Chris Smalling, Paddy McNair, Tyler Blackett; Antonio Valencia, Marouane Fellaini, MIchael Carrick, Angel di Maria, Luke Shaw; Wayne Rooney, Robin van Persie.

Subs: Anders Lindegaard, Darren Fletcher, Ander Herrera, Ashley Young, Adnan Januzaj, Juan Mata, James Wilson.
