Valuev and Chagaev are probably tops on the radar but I think both Dimitrenko and Chambers should get a look as well as they are fighting for a shot vs Wlad anyway.

I just think David Haye fits in with Povetkin and Solis....he's good, he's talented but has:
#1 NEVER been in with a big puncher
#2 NEVER been in with a top teir fighter
#3 NEVER fought anyone close to Wlad's size or style
