Manchester City swept aside Sunderland in the League Cup third round to add to Black Cats boss Dick Advocaat's woes.

Sergio Aguero opened the scoring from the penalty spot after Patrick van Aanholt fouled Jesus Navas.

Kevin de Bruyne shot past Vito Mannone, who then scored an unwitting own goal when Raheem Sterling's shot hit the post, struck him and went in.

Sterling completed the first-half rout from De Bruyne's cross, before Ola Toivonen netted a late consolation.

This was a fifth defeat in eight matches for Sunderland, who are bottom of the Premier League before their trip to Manchester United on Saturday.

By contrast, League Cup holders City rebounded impressively from their first defeat of the season against West Ham on Saturday.

Record signing De Bruyne was once again influential on only his second start for the club.

For Sunderland, the sole bright spot was the performance of debutant full-back DeAndre Yedlin, who supplied the cross for Toivonen's goal.

Rudy Gestede headed the only goal of the game as Aston Villa edged through to the fourth round of the League Cup with a derby victory over Birmingham City.

The Benin striker powerfully nodded in left-back Jordan Amavi's left-wing cross from 10 yards just after the hour mark.

Blues had the better of a highly charged first half at Villa Park.

But Villa got on top after the break to earn victory over Gary Rowett's side.

The visitors went closest in the first half through an angled shot from Jacques Maghoma, who also volleyed over when well placed.

And lively teenager Demarai Gray should have done better with a weak chipped free-kick straight at home keeper Brad Guzan.

 Unbeaten Leicester ended West Ham's three-match winning run on the road to progress into the fourth round of the League Cup with an extra-time winner.

Hammers keeper Adrian produced several brilliant saves but Andy King's header with four minutes left won the match.

Twenty-year-old striker Joe Dodoo, who hit a hat-trick in the previous round, opened the scoring with a fine finish from 10 yards.

Mauro Zarate levelled midway through the first half with a 25-yard drive.

Slaven Bilic's Hammers have won all three of their Premier League away games this season - at Arsenal, Liverpool and Manchester City - but were beaten by a Foxes side sitting fourth in the table.

The tie looked destined for a penalty shootout until King guided a Christian Fuchs cross into the top corner.

It was rough luck on Adrian, who denied Jeff Schlupp and Riyad Mahrez, as Leicester dominated the final half-hour.

Earlier, Leicester academy product Dodoo steered home from 15 yards on his full home debut, before Zarate beat Mark Schwarzer with a 25-yard shot that deflected off defender Marcin Wasilewski.

 Premier League Bournemouth survived a scare against Preston to reach the League Cup fourth round on penalties.

Shaun MacDonald's looping header gave Bournemouth the lead but substitute Jordan Hugill nodded the Championship side level to force extra time.

The Cherries took the lead again through Marc Pugh's close-range strike before Daniel Johnson levelled from the penalty spot.

Johnson had the decisive penalty saved by Adam Federici in the shootout.

Hugill and Alan Browne also had penalties saved, with home keeper Jordan Pickford denying Dan Gosling, as Bournemouth won the shootout 3-2.

The Lilywhites, who knocked Premier League Watford out in the previous round, were deservedly behind at the break after MacDonald took advantage of some poor defending to open the scoring.

Simon Grayson's men rallied after the break, though, and Hugill got on the end of Greg Cunningham's cross from the left to head a leveller with six minutes left.

Pugh was at the centre of the action in extra time, stabbing home after Josh King's shot was blocked, before Johnson punished his handball from the penalty spot.

Everton survived a scare against Reading as they came from behind to win their League Cup third-round tie.

Championship side Reading took a first-half lead through striker Nick Blackman as he finished a deep Ola John cross.

Ross Barkley volleyed in a low left-foot shot to equalise after the break as the hosts failed to clear a corner.

Gerard Deulofeu completed the comeback shortly after with a free-kick from 25 yards which Ali Al-Habsi could only parry onto the inside of the post.

Reading manager Steve Clarke made eight changes to his starting line-up, but it was the Royals who had the better of the first-half chances as Blackman forced two smart saves out of Joel Robles in the Everton goal.

Robles was again called in to action as Aaron Tshibola struck a fierce right-foot shot and centre-back Jake Cooper was just out of reach of finishing the resulting corner as he slid in at the back post.

But Everton's escape was short-lived as Blackman bundled in at the far post for his seventh goal of the season to give Reading a deserved lead.
