Wladimir's Klitschko's most possible loss?

I voted David Haye, as he already has experience fighting him. He knows what to expect. He wasn't blasted out, so a rematch may end differently. I would love to see a Klitschko/Solis fight (that goes past round 1). Mike Perez would also be interesting, as he is a southpaw. To be honest though, Wlad would be favoured in any of those fights.

I don't think there's anyone right now but i like the look of David Price he would certainly be able to match him in terms of size and talent, one to look forward to if Wlad is still around when Price is ready.

I think Odlanier Solis would be interesting (If his knee doesn't snap again)
