Good luck mate, either of the fighters are good, the odds says Kell Brook is the favorite, but it doesn't matter, what matters is what we think who would win the fight and if we believe on Amir Khan, we should gladly put our bets on him. Amir Khan and Kell Brook are both a decent fighter, it's just that they failed to hold on the belt to remain a champion, so let's support them as they will certainly entertain us.
Well, I just got the feeling to go with Amir Khan but yeah Kell Brook is an outstanding fighter and pretty much have the most experience, but the number of fights would surely not determine if the fighter would surely win, I could say that each fighter has their quality and both fighters could or may win against each other, but in my opinion, I could see there determination would make a great deal in defeating the other I think that Amir Khan is more determine in winning against Kell Brook, that is how I see it, and certainly, whatever the result this could be an entertaining fight I just wish this would not turn as negative as the grudge they have for each other.
I have almost the same idea as you, I often watch lightweight and world class boxing, the first thing I noticed was the movements and behavior of opponents A and B, during their interviews and meetings.
If i made a bet for them i would have judged their behavior, mostly what i guess worked, the match between Amir Khan vs. Kell Brook, In my opinion this is an unhealthy boxing match, they have a bad background that leads to revenge.
If Amir Khan faces Brook professionally and according to the boxing rules that apply Amir will determine his good career this time, If both of them are in the ring with the same emotions, this match will end in disaster for both of them, greater bloodshed will occur, meaning that boxing is not healthy on the basis of revenge.
I hope Amir can face Brook coldly and professionally without looking at Brook's current words.
I guess both fighters would surely face each other professionally even though they have a grudge for each other I think their professionalism with boxing will surely show when the fight comes, I still think that they still have great respect for each other and well maybe that stunt is just for the hype we may never know the real reason, but some fighters would exaggerate their engagement with one another surely to gain more Pay per view, or people would get interested, well if that grudge would be real it could surely get messy, but I would hope it is just for the hype.
