STEPHEN Broad is backing Chelsea to triumph in tonight’s FA Cup replay at Roots Hall. But he now also believes Blues do have a chance of causing an upset.

Broad spent five years at Stamford Bridge before joining Southend in March 2001. And he is looking forward to another battle between his two former sides.

“It’s going to be interesting and while I think Chelsea are going to win it’s not a certainty,” said Broad who 65 appearances as a defender for Southend.

“For Southend to go to Chelsea and draw 1-1 is just ridiculous. I was tracking the game on Soccer Saturday on the television and when news of the equaliser came through I just couldn’t believe it.

“They’ve done superbly and if they can just stay in the game tonight then they have a chance, even if it’s only a very slight one.”

Southend will be looking to pile more misery on a Chelsea side who have triumphed in only one of their last six matches.

And Broad, who now works as a taxi driver, does not think all is well with the Londoners.

“They look very disjointed at the moment,” he said.

“They are leaking goals too and that’s something which just isn’t like them at all.

“It hasn’t happened for at least the last five years and I’m sure Steve Tilson will be looking to take advantage of that.

“Both teams will also go into the game with Manchester United in their minds.

“Chelsea were well beaten 3-0 by them on Sunday, while Blues beat them a couple of years ago and that will give them belief.”
