I think he will lose his mandatory position with Garcia so the rematch will probably never happen (Angel Garcia, Danny's dad, is clearly against the idea as he probably knows his flat-footed son would lose and have his face busted up).
Its shameful actually that Canelo's team asked to fight Khan and not the other way round. As well as asking for a rematch clause... Fight GGG you coward and if not then vacate and let him have his belt!
Also i think Khan should have taken a tune up with Liam Smith (super-welterweight champion) to adjust at higher weight.
Anyway looking forward to it but cant see anything other than another KO loss for Khan.
