Tonight may be Manchester United's most important game in some time, but Jose Mourinho is sticking with Sergio Romero in goal. The Argentinean's been United's Europa League goalkeeper this far, has done pretty well, and his manager apparently trusts him to keep on going.
In front of him, it's an interesting selection. Neither Chris Smalling or Phil Jones are fit enough to start, so Eric Bailly and Daley Blind continue in the centre of defence, and and Antonio Valencia and Matteo Darmian take the full-back spots.
In midfield, Paul Pogba returns, to widespread rejoicing; the multi-million pound man may not have had the perfect season, but United look frankly staid without him. Speaking of staid, Marouane Fellaini starts as well, along with Ander Herrera.
On the attacking front, Marcus Rashford has Jesse Lingard and Henrikh Mkhitaryan for company. We're guessing they'll play wide and the youngster take point, but we don't really know. Maybe it'll be exciting and fluid.
On the bench we have David de Gea, Smalling, Ashley Young, Michael Carrick, Juan Mata, Anthony Martial, and Wayne Rooney. Which isn't too bad, all things told.
