And the third City change is...

Joao Cancelo?? No Raheem Sterling or Bernardo Silva.

Off comes Benjamin Mendy.

Fernandinho lofting a cross into the box and Charlie Raglan, cool as you like, heads the ball back to his goalkeeper.

That's confidence for you.

15 minutes remaining.

IS THIS HAPPENING???

I'd be very surprised if we didn't see Raheem Sterling soon.

City upping the ante and earn a succession of corners but Cheltenham manage to clear their lines.

Not happening for City, the longer it goes on the more they concerns will grow.

Again, Phil Foden picks out a peach of a pass through to Riyad Mahrez, but the Algerian's thumping strike from inside the area is kept out by the big frame of goalkeeper Josh Griffiths.

Pep has had enough and the teenagers are hooked.

Off come Taylor Harwood-Bellis and Tommy Doyle, Ruben Dias and Ilkay Gundogan enter the action.

Sean Long on for George Lloyd for Cheltenham and he will play scrum half.

Well, well, well.

Huge noise and celebrations from the Cheltenham Town contingent inside The Jonny-Rocks Stadium. Is the shock on the cards?

Suspect Pep Guardiola will be thinking about the likes of Raheem Sterling, Bernardo Silva and Ilkay Gundogan if this carries on much longer.

It looks like Ruben Dias will be first, which tells you what difficulty City are having with Ben Tozer's long throws. along with Gundogan.

Long way to go yet.

Plenty of time for City to get back into it.

Paul Collins: Get in Cheltenham. Saying that city should be winning this if they had a better striker than jesus who's more interested in falling over.

John Dunthorne: What a dangerous weapon a long throw in is.

Jezz: Cheltenham 1-0 Man City!!! The most surprising thing about that goal, is that it wasn’t scored by Tozer!!

Cheltenham skipper Ben Tozer is having a brilliant game at the back, sliding in to block Ferran Torres shot from the angle.

So we'll have Boyle and Dias on the same pitch.

NOOICE!

What?

City need a goal and Ruben Dias is getting ready to come on.

Incredible, absolutely incredible. That man Ben Tozer with the throw, great finish nipped in. Aymeric Laporte was fuming I think he thought he was pushed in the back. With no VAR there's nothing to see. Brilliant finish from Alfie May.

City are asking for a push, but not for me Clive.

Even VAR wouldn't have ruled that out.

THEY'VE SCORED!

Chris Clements whips in the corner but it is headed away at the far post by Aymeric Laporte.
