Brook by Stoppage he may lose a couple early rounds but as soon as he lands a clean power shot Khan will be in big trouble and Brook will finish him off probably by round 7
Depends on how fragile Kell's eye sockets are. Khan may not be a big puncher but he hits with enough velocity to hurt you. His speed is also a big factor in this too. Everyone is convinced that Kell is just going to time him and it is over but I am not so sure.
Brook by stoppage. Don't even see Khan outboxing him at points either, unless he gets Brook drained to within an inch of his life.
I hope Brook takes him clean out (and this from someone in Manchester close to where Khan is from). Brook is a much better boxer, very cute, skilled and with good power. I'm going with Brook mid-late KO.
