Kieron set for Chelsea

Kieron Dyer believes West Ham United will have to be at their best to upset Chelsea's Premier League title ambitions.

The England midfielder, who enjoyed a successful run out in last Saturday's 1-1 draw at Aston Villa, has identified Ivory Coast striker Didier Drogba and international team-mate Frank Lampard as the men to stop if the Hammers are to beat Guus Hiddink's side.

Dyer, who produced an encouraging display after appearing as a first-half substitute at Villa Park, is also eager to gave revenge for the 4-0 drubbing Chelsea dished out at the Boleyn Ground on 1 March last year.

With Liverpool also due to visit east London on 9 May, Dyer said the Hammers can have their say in the Premier League title race.

"We could have a great part to play in where the title goes this season. We've got Chelsea next and then Liverpool at home as well. Last season, Chelsea came to our place and gave us the run-around and beat us 4-0 so we have to redeem ourselves. With our injury situation it always seems to be backs against the wall, but we seem to be thriving on that."

Drogba has been in fine form in recent weeks, netting five goals in his last five matches including the winner in last weekend's FA Cup semi-final win over Arsenal at Wembley. Former Hammer Lampard, who was sent-off in last season's respective fixture, has plundered 20 goals for club and country this season.

"They have got match-winners all over the park but obviously Frank Lampard and Didier Drogba are the main two. Drogba has been like a new player and Frank is a 25-goal-a-season man, but they're not the only two we've got to worry about!

"We have to worry about their whole team and if we're going to get a result, we're going to have to have our eleven players on the pitch digging in. We can't carry anyone and can't have any passengers. Hopefully that will be enough because if their players all produce it's going to be an extremely hard game."
