Their bout will take place on February 8 in Manchester, UK.
"I didn't think so much about the fact that Chisora is at the end of his career, but I can point out that speed will be my key to beating him. I'm used to boxing on my opponent's turf and the home arena won't help him. I mean, I haven't had many fights in Sweden, so I'm always, you could say, in my hometowns, wherever I have to fight. Totally confident in myself and my victory. When I get in the ring, I just do my job to the best of my ability and that's it. So now we have to do the same thing and just listen to the judges' verdict," Boxing Scene quoted Vallin as saying.
