Man City beat West Ham 6-0 at Etihad Stadium

Alvaro Negredo netted a hat-trick as Manchester City demolished West Ham 6-0 in the Capital One Cup semi-final first leg.

Edin Dzeko grabbed two and Yaya Toure also got on the scoresheet as City all but booked a trip to

Wembley by piling on the misery for the Hammers and their under-fire manager Sam Allardyce.

Allardyce had prioritised the game to some extent by fielding a weakened side against Nottingham Forest in the FA Cup third round last weekend.

But that backfired as they were thrashed and despite eight changes, including the return of senior players such as Mark Noble, Joe Cole, Guy Demel and Mohamed Diame, it proved a similar story in the Manchester rain.

It was also a particularly chastening debut for Roger Johnson, who looked well off the pace after arriving on loan from Wolves to bolster the defence this week.

For City, it was another irresistible display to add to a growing catalogue that has already seen them put six past Arsenal and Tottenham and score seven against Norwich this season.

They might even have had more but for a number of good saves from Hammers goalkeeper Adrian.

Summer signing Negredo's treble took his tally for the season to 18, one behind injured team-mate Sergio Aguero.

The hosts certainly needed little time to break into their stride as they took immediate command of the game.

West Ham were troubled in the opening moments as Samir Nasri cut open their defence and Toure crossed looking for Pablo Zabaleta. The Argentinian was denied a shot but the ball rebounded and Adrian needed to keep out a ricochet off Negredo.

The warning signs were clearly there as Javi Garcia headed narrowly wide from a corner.

City took the lead as Toure, with plenty of time in the centre of the field, picked out Negredo with superb long ball. The Spaniard's technique was equally brilliant as he allowed the ball to drop over his shoulder before lashing a powerful left-footed volley into the bottom corner.

After that it seemed all too easy for City as Toure robbed Mohamed Diame to launch a raid that led to David Silva and Nasri testing Adrian from long range in quick succession.
