Michael Katsidis is expecting to play the villain's role but not for long when he fights local favourite Kevin Mitchell at the Boleyn Ground on 15 May.
The Australian boxer will be defending his interim WBO world lightweight title against Hammers fan Mitchell on the Upton Park pitch and knows he is in for a rough ride. However, he believes he can win over the London support as he did in a previous bout against Graham Earl at Wembley back in 2007.
Katsidis said: "My fight against Earl was like Rocky IV when Rocky has to go to Russia to face Ivan Drago. When the fight starts everyone hates him, but by the end they are on their feet cheering.
"Mitchell will do the same for my profile, and no one will be going home disappointed with the quality of the action. I've got this whole warrior image and it won't be changing it for this fight.
"There will be thousands of Aussies in the crowd as well, and when me and Kevin get it on, the atmosphere will be unbelievable."
