What a load of bollacks and proves the point that Khan never planned to move to the USA and train with a proven trainer. No real top trainer was going to devote time to trianing him in the UK so they opt for the 3rd choice. He may as well have stuck with Oli as Rubio is going to do fck all.
I think it's an act of cowardice on his part and a lack of ambition. If he was really serious about being the best, he'd give up his home comforts and base himself with a top trainer where he'd get top advice and sparring. But seems he doesn't want to be in a big pond and start from scratch in building up his reputation again, which is non-existent in the US.
