Phelps on Thursday confirmed on his retirement after the London Olympics.

Phelps won his 19th medal on Tuesday with gold in the 4x200 freestyle relay, and added his 20th by beating Ryan Lochte to gold in the 200 metres individual medley.

“When I spoke to him about sport, he said that he’d got so tired that these Olympics will be his last and his legs won’t be in the pool any more,” Latynina told R-Sport on Thursday.
