Sam has never played against Akpo, but the 33-year-old has warned there will be no love lost during the game.
"Because of the way I play I will just see him as another striker, which I'm paid to do. I'll probably just go through him and do what I have to do. I just hope he'll be OK," he said.
"I won't look at him as my brother on the pitch and I think he will do similar as well. He is a strong boy but I don't worry about that.
"The brotherly love will still be there, I just hope he knows I will not look at him as a brother in a tackle."
