90+2'- Mark Clattenburg blows his whistle to put Leeds out of their misery.

An early Yaya Toure goals was backed up by a brace from Sergio Aguero and a Carlos Tevez effort to claim a deserved win for Manchester City.

The Blues march on into the sixth round of the FA Cup, while Leeds have to return to the grind of the Championship.

Thanks for joining me, and make sure to stay tuned to Bleacher Report for all the coverage and reaction of a weekend of cup action.

90'- Dzeko flicks the ball up to Pablo Zabaleta who acrobatically volleys inches wide of Ashdown's goal. Almost five for City, there.

The Blues have conceded nine goals in the five cup games that they have played at the Etihad this season. It looks like a clean sheet today, though.

87'- Jamie Ashdown gets down quickly to stop Edin Dzeko's powerful strike from just outside the box. Great save by the Leeds keeper.

All that's left for City fans to do is to await the draw for the FA Cup sixth round, which will be held later today.

85'- Kolarov makes an excellent tackle near the corner flag to deny Byram a chance to cross.

With Leeds currently sitting in 12th place on the Championship table, eight points back from Middlesbrough in sixth, it's difficult to envision Neil Warnock's side threatening promotion this season.

82'- Sergio Aguero will miss out on a hat-trick today as Mancini makes his last change, bringing Edin Dzeko on for the Argentinian forward.

79'- Maicon gets involved as he breaks down the right flank, but his cross is well blocked by a retreating Leeds body.

Can Leeds give their travelling fans the consolation goal they deserve for their faithful support?

77'- With all the upsets and close affairs between mismatched teams we've seen in domestic competitions this season, one felt Leeds might have had a chance heading into today's game.

But the Blues have systematically and comprehensively torn their opponents to shreds. Yaya Toure, David Silva and Sergio Aguero the architects of a fantastic display.

74'- GOAL CITY!

It's Sergio Aguero again as he collects a fantastic through ball from David Silva and sidefoots his effort past Ashdown to make it 4-0 City.

73'- El Hadji Diouf runs at Kolarov before tumbling to the ground in acrobatic style. "Get up" says Clattenburg.

72'- Good chance Leeds as Luke Varney can't direct a free header on target from close range. Should have done better there.

70'- Steven Warnock delivers a searching cross from deep into the City box, but the ball evades everyone to bounce out for a goal kick.

Leeds haven't created much in the way of chances today, the likes of Kolo Toure and Matija Nastasic will have earned their night's sleep, tonight.

68'- Craziness in the Leeds box as Manchester City somehow fail to find a fourth goal.

Jamie Ashdown reacts sharply to stop Yaya Toure's initial effort, before Jack Rodwell's reaction header from close range bounces down off the underside of the crossbar.

67'- Alexsandar Kolarov wins a corner then takes it himself, delivering a poor effort that fails to clear Morison at the near post.

65'- As the game slowly drifts through the second half without much incident, Mancini feels comfortable to make another, more defensive change.

Carlos Tevez comes off for Brazilian Maicon.

62'- Jack Rodwell comes on to make his ninth appearance for the Blues. Javi Garcia is withdrawn by Roberto Mancini.

60'- Sergio Aguero gets to the byline, but Carlos Tevez can't stretch out far enough to meet his fellow Argentine's low cross.

The Leeds fans are still making plenty of noise in the away support section. Good on 'em, too.

57'- It's James Milner's turn to go close with a low effort that nestles in the side-netting of Jame Ashdown's goal.

Milner is of course a former Leeds player and still a genuine fan of the club.

55'- City immediately on the hunt for a fourth as Yaya Toure fires a rather tame (by his standards, at least) effort on goal from distance.

It's surely game over now as it becomes more a question of how many more can the Blues score?

52'- GOAL CITY!

It's a stunning team goal from the Blues as Carlos Tevez gets on the end of Sergio Aguero's cross-cum-shot. Great passing in the build up with Aguero key.

50'- Sporting an unsightly tissue stuffed into his mouth, the youngster is immediately allowed to come back onto the field.

It's the Leeds away support who are making all the noise at the moment. Not that they've seen anything special from their side here today.

48'- Byram goes down in his own box having been kicked in the face by a teammate.

The Leeds trainers rush onto the field as blood pours from his mouth. Nasty.

46'- We're back underway at the Etihad with Neil Warnock having made a couple of changes at the break.

Former Norwich striker Steve Morison is on in the place of Ross McCormack. Norris on for Brown as well in the midfield.

45+3'- The half time whistle blows and the Blues head to the break about as satisfied as they can be.

Early strikes from Yaya Toure and Sergio Aguero may just have killed off this fifth round tie before it ever got going.

Stay tuned for all the second half action.

47'- Tevez wins possession deep in the Leeds half. He lays the ball off to Milner, but his cross towards an unmarked Aguero at the far post is cut out by the last man.

45'- Ross McCormack fires an accurate free kick at goal from 25 yards out, but Pantimilon reads the forward's intentions perfectly and collects.

Three minutes of first half stoppage time to be played.
