Chelsea aims to derail Man United express

LONDON - Chelsea is determined to bring Manchester United's electrifying start to the season to a shuddering halt on Sunday as the Premier League rivals collide in a heavyweight clash at Old Trafford.

The Londoners travel to Manchester as underdogs, having already suffered three crucial defeats against Sir Alex Ferguson's men this year, losing in the league and Champions League at the tail-end of last season.

As if their poor recent record wasn't daunting enough, Chelsea is also facing a United side which has started the season in dazzling form, racking up four consecutive wins and notching an unprecedented 18 goals.
