David Haye will be weary of the jab which Wlad works off almost exclusively so both will be tentative. Wlad should look to drive Haye back in a straight line so that he can anticipate when exactly when Haye will move laterally (which he never punchers out from) so once moving (hopefully right), Wlad can nail him with a left hook.

What I'm saying is; if it ends early, it'll be with a left hook.
