Great noise at Bramall Lane as the teams emerge. This great old stadium is packed. Will the Blades respond by producing an upset?

What a chance for Lyle Foster! He's in behind the defence after winning possession in the Fleetwood half and only has the keeper to beat but he tries to chip him. Lynch stands his ground and it's a comfortable save in the end. Foster is kicking himself.

Club captain Harry Maguire and Bruno Fernandes hold the Carabao Cup aloft to all sides of the Old Trafford crowd.

Not much fuss, this is a team that wants more trophies. They will take a step closer to another one with a win today.

The biggest cheer was for Sir Alex Ferguson, presenting David de Gea with an award for breaking the club’s clean sheet record. There were also individual awards for Casemiro and United women keeper Mary Earps.

We’ve also had a minutes applause for legendary commentator John Motson before kick off.

Then the game starts and it takes 30 seconds before the first ‘Glazers Out’ chant of the match.

Great goalkeeping by Max Crocombe who rushes off his line to thwart Adam Armstrong. Moments later Alex Hunt is booked for a clattering challenge on Romeo Lavia. That was a proper League Two challenge!

Tottenham Hotspur

Tottenham's Son Heung-min, speaking to BBC Sport: "This is really important, the FA Cup is a big thing. This a tough place with a tough opponent but we are in a good momentum and we have to take that from the start of the game.

"Every game has been really important. Our focus is only on tonight. We need to be ready for this big game.

"We have to give everything to get to the next round."

Harvey Macadam plays it through to Shaun Rooney but it's well intercepted at the back by Burnley.

All Vincent Kompany's team so far and they go straight up the other end to mount an attack.

Half an hour gone. The League Two club have yet to register an attempt but they won't be too worried. They're still on level terms with their Premier League hosts.

League Cup champions Manchester United are under way against West Ham.

Billy Sharp is a lovable selfish centre forward who wants to play in every game. He is a box player, his movement in there is fabulous and he has great technique as well.

The players who are playing on a regular basis, the ones you would class as a first XI - look at the atmosphere here - they would want to play in this but you also have to look at the bigger picture.

Another chance for Saints. Carlos Alcaraz opts for a stooping header instead of a left foot finish and gets it horribly wrong.

A nice moment before kick-off at Old Trafford as goalkeeper Mary Earps and midfielder Casemiro are celebrated for their Fifa Best awards.

Aristote Nsiala almost gifts Burnley the lead with a pass back which was inches away from rolling into the back of the net!

His goalkeeper Jay Lynch was miles away and has to sprint back to stop it crossing the line.

Grimsby are caught in possession and a lightning attack ends with Mislav Orsic bending an attempt narrowly wide.

My 606 co-host Robbie Savage says Erik ten Hag is the best manager in the world following Manchester United's Carabao Cup triumph.

Ten Hag is doing an excellent job but I can't help thinking Robbie has got a bit carried away there, just for a change.

I can see why Manchester United fans are getting excited about what is to come, though. I also see them winning this tie pretty comfortably.

West Ham got a big win over Nottingham Forest on Saturday but they are still in trouble at the bottom of the Premier League table and they will definitely make changes with their weekend trip to Brighton in mind.

The Hammers looked more like the team they were last season with the way they attacked Forest, but we might see their second-string at Old Trafford and the result will reflect that, with a routine home win.

Sutton's prediction: 2-0

Burnley have dominated possession so far but Fleetwood look well organised. Scott Brown applauds on the touchline as they stop an attack down the right.

Grimsby were a non-league club last season but they're doing a good job frustrating Southampton midway through the first half.

West Ham manager David Moyes has praised the work Erik ten Hag is doing at Manchester United.

Moyes, who managed the Red Devils between May 2013 and April 2014, said: "Manchester United are a side that is used to success.

"I think they are climbing the ladder back up to where they want to be.

"[Ten Hag] has to get a lot of credit for the work he is doing. I can only look from a distance and admire the good work he is doing."

Sheffield United

Sheffield United boss Paul Heckingbottom has said he expects their FA Cup fifth-round tie against Tottenham to be a "special night".

The Blades are second in the Championship, while Tottenham are eight-time FA Cup winners.

"We have to perform in a way that gets the fans up and at it. There'll be moments when we have to suffer without the ball," Heckingbottom told BBC Radio Sheffield.

"I think it will be a special night regardless of the result."

He added: "It's one that all of us should enjoy because if we don't enjoy it we're not going to win anyway. It's not a distraction from the league, it's a good change."

Anass Zaroury is brought down just outside the box and wins a free-kick. It's curled in towards the near post but headed well wide by Ameen Al-Dakhil.
