Great Britain's James Guy has admitted that he "never thought" that he would win gold in the 200m freestyle final at the World Championships in Kazan, Russia.
The 19-year-old managed to edge out a competitive field of Sun Yang, Ryan Lochte, Chad le Clos and Cameron McEvoy to win gold in 1:45.14.
"It's quite nice to PB, I never thought I'd make the final," Guy told Eurosport. "I just [planned] to go out there and race hard and it paid off. I never thought I'd beat Sun Yang and [the others]. It's a huge race for me, I never thought I'd be on top."
Guy won silver in the 400m freestyle on Sunday.
