Scott McTominay admits Thursday's clash with AC Milan is Manchester United's biggest clash of the season.
The Europa League last-16 tie is level at 1-1 heading into the second leg in Italy.
"It will be tough. It's many years since I went there with Manchester United," McTominay said after beating West Ham on Sunday. "It's a chance to take a big step forward in our season.
"They are a tough team, everyone saw they have real quality. It's not a time to approach it any other way than full throttle and as if it's the biggest game of our season - which it is."
