Who has Ole picked to face Arsenal?

Romelu Lukaku and Alexis Sanchez are back for the Reds in attack with Jesse Lingard, who netted twice in the 3-1 Premier League win at the Emirates last season and against the Gunners in December, lending support.

Lukaku and Alexis are two of five players coming into Solskjaer's side; the others are Sergio Romero, Eric Bailly and Luke Shaw who replace David De Gea, Phil Jones and Diogo Dalot.

Lukaku scored in the third-round win against Reading at Old Trafford and this evening will be the first return to the Emirates Stadium for Alexis since his move to United last January.

Romero, meanwhile, will be between the posts for the Reds after keeping a clean sheet in that home win over the Royals in the last round. Shaw is back after illness forced him to miss the win over Brighton, while Bailly comes in for Jones in the centre of defence.

Paul Pogba, meanwhile, is making the 300th appearance of his club career as he looks to continue his excellent form of late.

Ole spoke to MUTV before the match and confirmed that Romero will be his chosen keeper for the FA Cup.

"You know that Sergio is a fantastic goalkeeper. When we looked at the whole season, Sergio is the FA Cup keeper. To keep players like him at this club, he needs to play in big games as well," explained Ole. "He is a fantastic keeper so I am looking forward to seeing him. He was Man of the Match against Reading, so I am very confident."

On having Alexis and Lukaku in attack, the manager added: "They give us something different. Obviously Rom with his physical presence, we might get some more crosses in for him, and Alexis has played here and played for them so I am sure he will be up for the game to show them what they have missed.

"We want to go for it, of course. We want to go through. To win this cup you need to beat a few good teams on the way and you can't get a bigger challenge than away to Arsenal in the cup. These are two clubs with fantastic traditions and histories in this cup."
