Irish swimming sensation Daniel Wiffen believes he is on a twin track to Olympic glory in Paris.
Wiffen, 21, swam PBs in Tokyo but has gone to a different level since last year - he broke the European 800m freestyle record in December.
In April, he posted the fourth-ever fastest time in the world at 1500m - 14:31.91 - only for a German rival, Florian Wellbrock, to beat it by 100th of a second a week later.
