Aston Villa are searching for an equaliser. They had 79.5% possession in the opening 15 minutes of the second half.

Chris Richards has once again just had to make a crucial block inside the box.

A lot of changes made by both sides, among them Matheus Nunes on for his Manchester City debut. He has replaced Phil Foden.

Erik ten Hag has just replaced Rasmus Hojlund with Anthony Martial.

The decision was greeted by a cacophony of boos.

The Manchester United fans do not like that at all.

Tottenham are pushing but still can't find a way through as Manor Solomon's latest strike flies wide.

Crucial block by Emiliano Martínez, who is off his line quickly to gobble up a rolling ball which Eberechi Eze was inches away from reaching.

Brighton are 2-0 up at Old Trafford and bring Ansu Fati on.

Wow.

Double change for both sides as Danny Welbeck and Adam Lallana come off for debutant Ansu Fati and Joao Pedro.

Rasmus Hojlund comes off Anthony Martial and Hannibal Mejbri comes on for Casemiro.

Erik ten Hag's decision to bring off Hojlund is met with loud boos from the home supporters.

Jack Robinson becomes the latest Sheffield United player to get booked for timewasting. One of those days for Spurs.

Ollie Watkins' header is picked out by Sam Johnstone at the back post.

Leon Bailey has made an impact since coming on.

Jim in Fulham: Fulham remind me of a boat tacking back and forth against the wind to make forward progress (I admit this is a very Fulham fan metaphor).

Tottenham still can't carve through Sheffield United as a Yves Bissouma headed effort drops wide before Manor Solomon curls a shot from range over the bar.

Villa are furious as they think they should have a penalty. Moussa Diaby slips it through to Ollie Watkins.

He swipes to shoot and catches Joel Ward, who got there first. Cheick Doucoure also got there first and is hurt after slipping as he made contact with the ball.

Alex Iwobi is on for Fulham, making his first appearance for the club since joining from Everton.

Will he make an impact?

Brilliant save by Ederson!

The Manchester City goalkeeper reacts well to dive to his left and push away Kurt Zouma's header.

Here come the first changes at Villa Park. Leon Bailey and Youri Tielemans are on for Boubacar Kamara and Nicolo Zaniolo for Villa.

It's funny, this might actually be Manchester United's best performance of the season.

They haven't looked like scoring though as Marcus Rashford's latest effort deflects behind for a corner.

This is the second successive home league game in which Manchester United have trailed 2-0.

Against Nottingham Forest last month, they turned it around to secure a memorable victory.

Doing it again - against Brighton - is a whole different matter.

Seth: I'm sorry to say it but De Zerbi is schooling Ten Hag here.

Stephen: Let’s be honest, ten Hag is no improvement on Ole. It’s like the Van Gaal days again.

Anonymous: Ten Hag gets out-coached by every manager he faces. Man Utd deserves better than that.

Sheffield United are getting a little desperate now as a lazy challenge from Olivie McBurnie to break up an attack sees the forward rightly shown a yellow.

Moments later Jack Robinson is in the right place at the right time to block Son Heung-Min's effort.
