Allardyce was in charge of Blackburn when he engaged in a series of public confrontations with the then-Liverpool manager Benitez.

However, the Hammers boss insists any problems are now in the past and adds he is focused solely on the game ahead, as they prepare to welcome Benitez's Chelsea to Upton Park for their London derby.

"It was a long time ago, a lot of water has gone under the bridge since then and I am just looking forward to the game," Allardyce told reporters.

"I don't want to jump into that scenario, I am a bit bigger than that, I don't want to go tit for tat.

"All I do is look to compete at a level going against not just Chelsea, but also against a man who has a real good record, to see if we can upset them."

Ahead of the derby, Allardyce believes Benitez's Chelsea side are still a dangerous prospect and does not want to let a run of just two wins in 10 fool him.

"In the last two games they have not conceded a goal," he added. "At the heart of every good side is producing a clean sheet.

"Rafa has already sorted out what was a problem under former manager Roberto Di Matteo, and now they have got a couple of clean sheets in a row, so it will not be long before they can turn that into a victory if they continue to defend like that.

"It will be more difficult to break Chelsea down than it would have been, chances will be few and far between."
