SAM Allardyce wants Wanderers fans to create a Reebok Roar that will frighten the life out of Middlesbrough on Sunday.

Allardyce believes a passionate capacity crowd can spur the team to the victory which will preserve the Whites' Premiership lives.

The manager today called on the fans to turn the Reebok into a cauldron of noise that will stop Boro in their tracks and drive Wanderers on to a famous triumph.

He wants the fourth consecutive sell-out Reebok crowd to turn up the volume so much it will intimidate Steve McClaren's men and give Wanderers a crucial advantage.

Victory on Sunday would complete the remarkable achievement of Wanderers remaining in the top flight for three successive seasons on a shoestring budget.

It would be the first time Wanderers had remained in the top division for more than two straight seasons for more than 40 years.

The Wanderers camp know there is a lot of work to do first and they want the supporters to shake off the nervous tension and help them achieve it by creating the most partisan atmosphere of the season.

Allardyce believes the fans can give his players a head start over Boro by turning the Reebok into a mass of colour and a den of deafening noise.

He said: "Sunday is without doubt the most important day in the recent history of the club.

"I am urging our supporters to create a cauldron of noise and passion.

"I want them to make the atmosphere as intimidating as possible.

"I would love to see the supporters waving flags, wearing colours and in full voice.

"We all know what the power of support can do. The support we have received all season has been excellent and in particular over the last three games."

To stay up Wanderers have to match or better West Ham's result at Birmingham City.

In theory the Whites could stay up with a defeat - as long as the Hammers lose at St Andrews.

But Allardyce wants his team's supporters to ignore what is happening elsewhere and concentrate on lifting their side to a historic victory.

"It's in our hands," he added. "We can do it. We only want positive reactions from our fans and we don't want to hear anything about what is happening elsewhere."
