The last time these two sides played at King Power Stadium, on 26 December, it was a cracking game that ended up 2-2.

I'm expecting it to be quite open this time too and I just have a feeling the Foxes will edge it.

But, whether they win or lose this tie, both teams are on course for successful seasons. A top-four finish would make sure of that on its own - going on and winning the FA Cup would be like the cherry on the top.

Prediction: 2-1

Tom: Inviting Leicester forward with Fred (pass it back) and Matic (shall I pass or not?) in the same team. Hoping the front players keep the ball away from them

It has ended West Ham 3-3 Arsenal in the Premier League after the Hammers led 3-0. Get reaction here.

Leicester hold the unenviable record for most FA Cup final appearances without winning the trophy. The last of their four finals came in 1969.

The Foxes have not reached the FA Cup semi-finals since 1982; they have since lost five quarter-finals, the last three of them all against Chelsea (2020, 2018, 2012).

Manchester United have won the FA Cup 12 times, second only to Arsenal's 14.

The Red Devils are looking to reach the semi-finals for a record 31st time, surpassing Arsenal.

United are in the quarter-finals for a club record-extending seventh consecutive season.

Manchester United

Manchester United boss Ole Gunnar Solskjaer speaking to BBC One: "We expect them to be a tough challenge, very technically good team, pace up front, scoring goals. Coming back from Italy we needed to make a few changes but we're up for it - we want to come here and do what we've done the last few times we've been here because we've done well.

On having Paul Pogba back: "It's going to be massive for us the last two months - Paul has been a big miss for us he hasn't been at full fitness but he's been training well and we know how good he can be for us."

On Dean Henderson starting over David de Gea: "David went home for 10 days and didn't train and has come back and trained well and is ready to go off with Spain - but the last two months you will definitely see the two of them."

Leicester City

Leicester boss Brendan Rodgers speaking to BBC One: "We've got to make a good start. When you've had a midweek European game it's important that you can start well and be aggressive without the ball.

"When you can't press the game we've got to be compact and defend well because we know the quality that they have going forward. I'm confident we can create chances and, if they come, be clinical."

Leicester's only win in the past 25 meetings - spanning 23 years - was by 5-3 at the King Power Stadium in the Premier League in September 2014 (W1, D5, L19).

That is their solitary home victory over United in 14 attempts.

Manchester United won both previous FA Cup meetings: 3-1 in the 1963 final and 2-1 away in the fifth round in 1975-76.

Brendan Rodgers has lost 11 of his 14 meetings with United, failing to win any of the last seven.

Premier League

Arsenal have just scored their first actual goal of the game - an Alexandre Lacazette header - to make it 3-3 at West Ham. A thriller.

Leicester have been doing so well - they've had some injuries to very important players, missing James Justin who has been a massive signing for them. But Brendan Rodgers has taken this club forward and I think there's big things to come from Leicester.

Manchester United

Manchester United haven't won a trophy since the 2017 Europa League. Boss Ole Gunnar Solskjaer hasn't won one since the 2013 Norwegian Cup.

He said: "Sometimes it [winning trophies] can hide the fact what you're doing in the background but I feel we are improving all the time and getting closer and to win a trophy would be a boost for everyone.

"We've had this before when we won the Carling Cup in 2006 with Nemanja Vidic and Patrice Evra, their first wins and it was the first of many. We feel or hope a trophy can be a catalyst of more to come."

Michael Devlin: Don’t understand this second rate United lineup. Doesn’t Ole want to win something? The league is gone. Why not take a run at the FA Cup?

Francesca Gunn: Seriously not playing Bruno!!! Switch Fred or matic out for him, pogba works off Bruno and vice versa

Premier League

It's West Ham 3-2 Arsenal in the Premier League now. Two own goals have brought it back from 3-0. Follow the final 30 minutes here.

Leicester City manager Brendan Rodgers told Gary Lineker that Jamie Vardy is "frightened of no-one".

Watch the Football Focus interview below.

Leicester boss Brendan Rodgers has praised Kelechi Iheanacho after a run of seven goals in eight games.

He has lifted some of the goalscoring pressure off Jamie Vardy, who has scored once in his past 15 matches.

"Kelechi has got huge personality," Rodgers said.

"He respects his life as a footballer, respect his friendships he has within the team and appreciates all the support he gets from everyone.

"He trains so hard and is like any player, when they are confident they play the game to a new level and another dimension. That is where he is at. He has been really productive but he knows he has to continue with that.

"He plays with a smile on his face, very rarely does he miss training. There have been some performances when he hasn't been at his most confident but he gives his all."

Just the one change for Leicester from the side that thumped Sheffield United 5-0 last week as Marc Albrighton comes in for the injured Ricardo Pereira.

Kelechi Iheanacho grabbed a hat-trick in that match and he starts up front alongside Jamie Vardy.

Leicester City: Schmeichel, Fofana, Evans, Soyuncu, Albrighton, Ndidi, Tielemans, Castagne, Perez, Iheanacho, Vardy.

Subs: Ward, Fuchs, Thomas, Daley-Campbell, Praet, Amartey, Choudhury, Mendy, Leshabela.

Five changes for Manchester United from the side that won 1-0 at AC Milan on Thursday to move into the Europa League quarter-finals.

Paul Pogba, who scored the only goal at the San Siro, starts, as do Alex Telles, Nemanja Matic, Donny van de Beek and Anthony Martial.

Bruno Fernandes drops to the bench, while Edinson Cavani is also a substitute after injury.

Manchester United: Henderson, Telles, Maguire, Lindelof, Wan-Bissaka, Fred, Matic, Van de Beek, Pogba, Martial, Greenwood.

Subs: De Gea, Shaw, Fernandes, Williams, Tuanzebe, James, McTominay, Cavani, Diallo.

The last time the two sides met in a game outside of the Premier League was the Community Shield at Wembley Stadium in 2016.

Leicester were Premier League champions after a stunning 2015-16 campaign, while Louis van Gaal lifted the FA Cup, in what proved his final match as United boss, thanks to an extra-time victory over Crystal Palace.

United managed to outfox the Foxes in August 2016 - so how many of the starting XIs from that day can you name?

It should be a cracking game. Both teams will be desperate to get to the semi-finals so hopefully there will be a few goals.

Both clubs will have reasons why they need and want to try to win the competition. Leicester have never won it, Man Utd have won it 12 times. It'll be an extra incentive for a great game.

BBC One build-up starts at 16:30 GMT

Listen to BBC Radio 5 Live's Football Daily.

It includes an interview with Leicester defender Timothy Castagne - and the team of journalists and former players discuss the importance of winning trophies.
