Past the half hour mark but City still yet to break the deadlock.

Benjamin Mendy finds Phil Foden in the box but the youngsters fires a first-time shot wide.

He should do better and he knows it.

Mancheter City are a big threat, inevitably, but Cheltenham Town are competing really well. Alfie May excellent after recovering from a very heavy early collision with the advertising boards.

Keepersssss!

Chris Clements lofts a long free-kick into the box but City goalkeeper Zac Steffens show save hands with a clean catch.

The Boyles, they all wear beige.

Cool, cool, cool, cool, cool, cool, cool.

Will Boyle looked surprised, you don't get yellows for that in League Two do you?

Have a watch of this...

Boyle on Doyle.

Will Boyle does lunging in on Tommy Doyle and gets the first booking of the game.

Fenners: Isn't it nice to watch a game without VAR !!!

Oooh, Cheltenham close to a shock lead.

Finn Azaz plays a good ball through to Alfie May in on goal, the Cheltenham strikers tries to catch out Zac Steffens at the near post with an early strike but the American goalkeeper reacts sharply to tip the ball wide.

City starting to take control of possession though, knocking some nice cross-field passes from right to left and back.

Riyad Mahrez whips in a cross to the back post at the end of the move, but Gabriel Jesus mis-times his jump and shoulders the effort wide.

Riyad Mahrez has such good feet he must be a nightmare to play against, his balance is superb, the ability to twist and turn.

20 minutes gone and City are being kept at arms length by League Two Cheltenham.

City almost punish Cheltenham for a loose pass, Phil Foden finding Ferran Torres in the box, but the Spaniard's low shot from eight yards out is pushed away by Josh Griffiths.

A decent save that.

Cheltenham defender Ben Tozer got to the ball before Ferran Torres there and surprise surprise, there is nothing wrong with the Spaniard.

Man City forward Ferran Torres goes down in the box with a scream that they've heard in Gloucester but referee says NO.

How has he cleared that off the line? A great ball from Taylor Harwood-Bellis, whipped in with pace, but brilliant defending from Ben Tozer.

Ben Tozer's clearance was superb, but not as good as this from the first round...

How has this stayed out???

The ball breaks loose at the far edge of the box and Benjamin Mendy smashes a first-time strike which is arrowing towards the corner, but Cheltenham skipper Ben Tozer somehow manages to get his body in the way and divert the ball away from goal.

A superb clearance.

A sniff for City but the header from Aymeric Laporte is straight at Josh Griffiths.
