Clayton, 37, competed in the 200m and 4x100m at the 2000 Olympic Games in Sydney
The personal trainer responsible for keeping Cristiano Ronaldo in top shape has been revealed as former British Olympic sprinter Samantha Clayton.
Ronaldo has developed into one of the finest athletes in world football and is rarely afraid to show off the fruit of his labour.
And the woman who has played a key role in helping the Portuguese star reach peak physical condition is Liverpool-born Clayton – who competed at the 2000 Olympics.

Ronaldo met the former sprinter and nutrition expert through her work with American sports nutrition company Herbalife.
The pair are now working to improve the speed of the Real Madrid star – who has won 29 team and individual gongs during his career.
