Witter just called out Hatton, and to be honest I wouldn't mind seeing it. Witter is on Golden Boy Promotions right? I'd love to see Hatton go back down to 140, win the WBC, have a couple more fights and retire on a high - but really he doesn't have much to prove (options are limited), it'd just be great to see Ricky bounce back again.
Khan is very quickly outgrowing the domestic scene, like Frank Warren said, he's ahead of schedule. But he needs to get the best trainer money can buy in order to step up to the next level - but not before fighting either Thaxton or Melero. Training in the US, with top quality sparring partners will accelerate his growth and get him to a stage where he's a realistic contender. He's already visited Freddie Roach's gym and been on the pads with him, if he heads over to the US more often, the he's definitely on the right track.
