Randy Couture talks to Cagewriter about the possibility of Fedor Emelianenko coming to the UFC, and the fact that it was in his contract when he re signed with the UFC that they would work to sign Fedor so that he would be able to fight him:

"Not only do I think I deserve a shot at him, it's kind of part of the agreement in settling our differences in coming back to the UFC, is they were going to be diligent about trying to find a way to make that fight happen."

I'm not sure, but I think that was before Couture got mauled by Brock Lesnar.
