Phelps greatest Olympian as Ye claims second gold

Four years after he climbed to the top of Olympic achievement, Michael Phelps took the last step he needed to reach the absolute peak.

The greatest swimmer of all time became the most decorated Olympian of all time when he won a record 19th Olympic medal at the London Games last night.

With a little help from his American friends, Phelps won his first gold medal in London in the 4x200 metres freestyle less than an hour after a shock defeat in the 200 butterfly, an event he has dominated for over a decade.
