West Ham United fans are being urged to make some noise tonight against Wolves.
Hammers co-owner David Sullivan is determined to make Upton Park a fortress and knows the importance of getting a victory over Wolves, who sit just one place above the Hammers in the table.
Shirt sponsors SBOBET have backed a giveaway of 30,000 clap-banners. They are inflatable tubes that can be folded to smash together.
The claret and blue clap-banners feature the words 'Come on you Irons' and will be available to every home fan in their seat.
Sullivan is pleading with them to make it a deafening atmosphere for the Wolves players.
He said: "To our most loyal 34,000 fans, I'd like to say a special 'Thank you'.
"We rely on the fans the most - especially those who have forked out for season tickets and memberships.
"We are so proud of them all and will never take them for granted.
"We hope to give every fan a free gift to put some more fun into the match experience for everyone.
"We need to make as much noise as we can to make this a stadium that away teams fear."
