Magnussen 'mentally stronger'

World 100m freestyle champion James Magnussen has said that the lows he experienced after the London Olympics have made him appreciate the highs of victory after he retained his world title in Barcelona.

The Australian missed out on gold last year by a mere one hundredth of a second to America's Nathan Adrian.

But he gained some measure of revenge on Thursday when he pipped Adrian and James Feigen, also of the US, to take victory.
