Last Sunday, Man United suffered a 2 - 0 loss to Crystal Palace at Old Trafford, continuing a dismal run of form not seen since the 19th century.

In this competition's third round, Amorim led his side to famous wins at Man City and Arsenal. Meanwhile, Nottingham Forest, Bournemouth, Newcastle, Brighton & Hove Albion, and Palace have all easily claimed victories at Old Trafford.

The Red Devils are languishing in 13th place in the bottom half of the table, just three points above 16th - placed Everton. So, the FA Cup and the Europa League are likely their only chances to return to European competitions.

This is a favourable draw for the hosts, and being at home should help too, considering they have not lost any of their last 18 FA Cup ties at Old Trafford in regular time - winning 16, as the last visiting side to win here was Arsenal back in the 2014-15 season.

Leicester are a side they have already gotten the better of multiple times this season too, and peculiarly, the opposition manager was the man who earned both of those wins for Man United.

Ruud van Nistelrooy was in the dugout for United for the 5-2 and 3-0 wins in the EFL Cup and Premier League respectively, before being appointed Leicester's manager a few weeks later.

That gives Man United the opportunity to beat a club three times at home in a single season for the first time in their history, but after winning the first two FA Cup meeting with the Foxes, they lost the most recent in 2021, with Leicester winning a quarter-final clash at the King Power on the way to lifting the trophy that season.

It was in the quarter-finals where Leicester were eliminated last season as a Championship club, going down to Chelsea, but morale is nowhere near as high as it was last season, and despite Man United's struggles, the Foxes are in even worse form.

Even extending their run of seven wins from their last eight fourth-round ties looks a stretch, especially after being brought back down to earth at Goodison Park last weekend.

Just a week after a sensational win away to Tottenham Hotspur, Leicester were thrashed 4-0 by Everton, allowing the Toffees to move nine points clear of them in the battle to avoid the drop.

Wolves' win later that same day at home to Aston Villa saw them fall back into the bottom three following a run of eight defeats in nine games, and no notable additions were made in the transfer market, making Van Nistelrooy's job much tougher.

Marcus Rashford left Man United at the end of the transfer window, while Alejandro Garnacho stayed put, but Amorim's wish for a striker was not granted, just days after he selected Kobbie Mainoo as a false nine over Rasmus Hojlund and Joshua Zirkzee.

Lisandro Martinez's season is over after he tore his ACL in the defeat to Palace last weekend, joining Luke Shaw, Jonny Evans and Mason Mount on the sidelines, while Tyrell Malacia has left for PSV Eindhoven on loan.

Patrick Dorgu joined as one of their late signings in the window, and could make his debut here, while Altay Bayindir is also set for a rare start, especially after his heroics in the third-round win over Arsenal.

Mads Hermansen returned from a six-week layoff at Everton last weekend, but has not played in either cup competition so far, so Jakub Stolarczyk could come back into the side here.

Wilfred Ndidi is edging closer to a return from a thigh injury, but Ricardo Pereira and Abdul Fatawu remain out with long-term setbacks.

Van Nistelrooy may go more offensive following their horror show at Everton, so Facundo Buonanotte and Stephy Mavididi may be drafted in out wide, while Jannik Vestergaard is likely to lose his place in the side.

Manchester United possible starting lineup:

Bayindir; Mazraoui, Maguire, De Ligt; Dalot, Ugarte, Mainoo, Dorgu; Amad, Hojlund, Fernandes

Leicester City possible starting lineup:

Stolarczyk; Coulibaly, Coady, Okoli, Kristiansen; Soumare, Skipp; Buonanotte, El Khannouss, Mavididi; Daka
