Swansea v Chelsea preview: Michael Laudrup says Swans will attack wounded Blues

The Welsh outfit, who have never won a major trophy, take a two-goal lead into the second leg semi-final at the Liberty Stadium having stunned the European champions in the first half of the tie at Stamford Bridge two weeks ago.

Michu and Danny Graham scored the crucial goals that night, leaving Chelsea with an uphill struggle at a ground where they have been held to league draws in the last two seasons.

Nonetheless Swans manager Laudrup knows that Chelsea remain a threat, but believes defence could be the best form of attack.

He said: “They have been much better away than at home. They won 4-0 at Stoke, they got five against Southampton and against Leeds. They also won at Everton, so they are maybe the best away team in the Premier League.

“It is different to start a game from 0-0 rather than 2-0, but the only danger is if we think can go out and just defend. Ninety minutes is a very long time to do that.

“We have to be prepared to do a little of both. We have to try and get on the ball and look to attack, although we know there will be moments when we have to accept we will have to defend.”

Centre-back Chico Flores (knee) is fit again for the home side, while Chelsea’s club captain John Terry is in contention for a first start since November.

Chelsea confirmed today that England left-back Ashley Cole has signed a one-year contract extension with the club.

Cole said: “I wanted to stay at Chelsea because we are always fighting and challenging for trophies.”
