Villa carve out a response to going behind as Rudy Gestede latches on to a loose ball, but Ashley Westwood can only tamely shoot straight at Maarten Stekelenburg.

Kevin MacDonald throws on Jordan Ayew and Jack Grealish off the bench before Gabby Agbonlahor forces Stekelenburg to tip a bending right-foot shot over the bar. 

Harry Arter has looked lively in his first appearance of the season - little rustiness from the Bournemouth midfielder. He slopes foward from central midfield, only to see Martin Skrtel stick his bulky frame in the way. Nicely poised is this cup tie...

Kevin de Bruyne is in on goal, great ball from Wilf Bony, De Bruyne onto his right foot - is this three...? No! Wayne Hennessey saves with his face. Put your body on the line!

And our final game of the night is back up and running.

Manchester United captain Wayne Rooney is on at the break in place of James Wilson.

Roberto Firmino might as well be wearing his sharpest suit and a good soak of his finest aftershave - he is desperate to impress the Liverpool fans tonight. The Brazilian woos the home crowd again, picking the pocket of Cherries midfielder Marc Pugh, only to drive his low shot across the face of goal.

"Pablo Zabaleta has been in the wars already tonight, after his clash of heads with Yannick Bonasie, and it is curtains for the City defender this time - he is carried off with his leg heavily strapped, after several minutes of treatment, and this looks serious.

"Bacary Sagna comes on at right-back instead, as Zabaleta exits to a standing ovation and the sound of City fans singing his name."

Alan Hutton looks a bit dazed and confused after he comes off worse in a collision with his own goalkeeper Brad Guzan.

A dinked ball into the area towards Graziano Pelle had Guzan rushing off his line to punch clear, but he took his right-back with him.

Hutton's back on though after some treatment from the magic sponge.

Man City 2-0 Crystal Palace

Bad news for Manchester City fans as popular right-back Pablo Zabaleta has to leave the field on a stretcher. Is that a muscular problem?

Contender for miss of the season by Wilfried Bony after more great work by Kelechi Iheancho and Fernando to tee him up.

The Nigerian's precise ball released the Brazilian, and he unselfishly squared for the Ivorian, but Bony skied his first-time shot high over the bar from about 10 yards out, before staring accusingly at the ground, Sunday League style, as if to blame a bobble.

He was unmarked too, and had time to take a touch, so that is no excuse.

And now Palace go so close! Mile Jedinak flicks on a header, Willy Caballero is nowhere, and Martin Demichelis does well to get back and clear from off the line.

The Kop roars its approval as Liverpool attack arguably the most famous stand in English football. Neat footwork from both Roberto Firmino and Jordan Ibe almost create chances for the home side.

Oh what a chance! Fernando puts it on a plate for Wilfried Bony but he fires it well over the bar! Huge miss. That was the quarter-finals right there...

Early chance for Bournemouth! Junior Stanislas's deep corner is met by the head of the leaping Shaun MacDonald, but the Cherries midfielder sees his effort just shave the wide post. Suspicions of a penalty, perhaps? Possibly. MacDonald is manhandled as he jumps but referee Mike Jones sees nothing wrong there.

Back under way for the second half here and it's fair to say my highlight so far has been the half-time pies laid on for the press.

But, Graziano Pelle combines with James Ward-Prowse for Southampton and the Italian's shot is deflected just wide for a corner.

Will that help up the tempo? 

We are back under way at City too.
