Although we’re only a couple of days into the Olympic games, fans of Michael Phelps are worried that he won’t be able to recapture the lightning he bottled four years ago, as he has yet to score a medal. And although he only needs two more to become the most decorated athlete ever to participate in the games, some are wondering if he’ll be able to pull it off.

Described as “tired and sluggish” during the 200 meter butterfly semi-finals, he admitted that at least one of his finals swims didn’t go the way he wanted it to and went so far as to call it “crappy”. In several races, he’s managed to only just make the finals by the skin of his teeth, which is unlike him.

But Phelps says that he was happy with this morning’s butterfly semi-finals–which earned him a spot in tonight’s race–and insists that while he’s tired, he’s not alone.

“I guess I got to bed pretty late. We’re all falling asleep pretty late. We’re all excited,” he said.

But while Phelps has some stiff competition this year, he certainly seems to be intent on proving he can do what he came here to do, and if he doesn’t close out the games with more medals than any other Olympian in history, it will be a shock.
