I think it would be a great idea to send Khan on a few training camps with some foreign coaches just so they can drum some of the reality beyond British shores into him, but on the other hand I think Harrison is getting him up for fights and preparing him fairly well, so in the build up to fights I see no problems letting him come back.

He's been developing well, and fighting often, but it might be an idea to give Khan a few months off to learn about boxing in the states or other territories with coaches over there, and get in some quality sparring that will test him in fairly safe grounds. After all, he's really still a kid with years of growing into the sport ahead of him.
