Marouane Fellaini pulls the ball back for Wayne Rooney, whose shot is at Kasper Schmeichel.

Danny Murphy says the pass "should have been softer. He drilled it at him".

Nick Rivers: 

32mins Everyone puts lingard in their fantasy team. 

62mins Everyone takes him out. 

He had his boot and sock off after coming off and was getting treatment.

They're doing the applause now for England winning the 1966 World Cup...

Kyle: Whatever happens Leicester will be great to watch again. They have to be the quickest with Musa, Vardy and Mahrez.

Yahya magaji hammado: Leicester summer signing Ahmed Musa is showing his capability - speed, pass and dribbling 

A lot of the remainder of this live text will be reporting substitutions, I fear. Each club get six. Jose Mourinho is chatting to Marcus Rashford now.

Look away now Marouane Fellaini...

It's a great decision that this will go straight to penalties if the scores are level after 90 minutes. I would bin extra time completely in all the competitions - it would make players go for it in 90 minutes.

And here they come. Leicester bring on Nampalys Mendy, seen as N'Golo Kante's replacement, for Andy King. 

Right-back Danny Simpson comes off and Luis Hernandez, another summer signing, comes on.

And another United change too, Jesse Lingard, who appears to be injured, is replaced by Juan Mata.

Ander Herrera replaces Michael Carrick for Manchester United - it's Jose Mourinho's first change of the night. Looks like Leicester getting another couple of subs ready.

Nikhil Jadva: Classic Fellaini. Picking up where he left off from last season 

Nathan: And that's why pogba will be playing and Fellaini will be warming the sub bench. 

Andrew Reyes: Dear David Moyes, please please please can you sign Fellaini? 

Robin Peckitt: Fellaini is TERRIBLE! How on Earth is he staying ahead of Schweinsteiger?! 

Roger Whittington: And with the arrival of pogba that's fellaini's last game #Pogback, external

A very common theme on the tweets emerging...

Leicester City are looking confident now and Ahmed Musa finds fellow substitute Demarai Gray, whose shot from outside the box is saved by David de Gea.

Will Jose Mourinho be thinking about a substitution of his own now?

The Manchester United fans in front of me are on their feet again but a lot angrier than they were earlier. No prizes for guessing who their fury is directed at... yes, Marouane Fellaini, who got roundly booed when he touched the ball for the first time after gifting Leicester their equaliser.  

The Leicester end is still bouncing, with their fans' favourite chant 'champions of England, we know what we are' coming across loud and clear.

Leicester midfielder Andy King goes into the book for a sliding tackle on Jesse Lingard.

That's Leicester's first shot on target.

That was a really poor back pass by Marouane Fellaini but Jamie Vardy was really quick to get on it. Great anticipation by Vardy but sloppy by Fellaini. Leicester have been gifted a way back into the game.

All the best teams when they have won the Premier League in the past have bought three or four new big signings to strengthen their first XI. Leicester have not done that. 

Danny Drinkwater plays a great pass to Riyad Mahrez, the ball ends up with Ahmed Musa and the new signing tries to play it to Jamie Vardy but, again, didn't quite get the weighting right.

Promising signs for Leicester though.

Ahmed Musa tries an ambitious through ball to Jamie Vardy but it's not very good and United clear. It'll take him a while to have a near-telepathic bond like Danny Drinkwater and Riyad Mahrez had with him last season.

Michael Carrick brings down Jamie Vardy and concedes a free-kick. But Leicester don't do much with it and seconds later it's with their goalkeeper Kasper Schmeichel.
