US swimming great Michael Phelps returned to China Wednesday looking for the form that swept him into the history books at the Beijing Olympics, as a major doping row clouded the world championships. Phelps, who has caused concern with some stuttering swims this year, made a low-key arrival at Shanghai’s Pudong Airport, looking unshaven and wearing a baseball cap. He did not speak to media and was whisked away on a USA team bus. “Weeeee twitter DOES work!!! Here at last,” he tweeted afterwards, referring to China’s
ban on the popular microblogging site.
