After Ronaldo got the ball rolling with an impressive 142 crunches in 45 seconds, Arsenal youngster Saliba took his turn.

However the Saint-Etienne loanee, 19, showed he has plenty more developing to do before matching a powerhouse like Ronaldo - tallying 65.

Still, teammates and fans gave Saliba a pat on the back for giving the challenge his all in the face of stiff competition.

Saint-Etienne goalkeeper Stefan Bajic wrote on Instagram: "Wilo, Cristiano and Messi the world top three."

A Gooner added: "Beast can't wait to see you in an Arsenal kit next season."

Another fan replied: "My Centre Back. Bondy’s finest."
Manchester United playmaker Fernandes also came up short of Ronaldo's total, notching 117 reps while the Portuguese star's Juventus teammate Blaise Matuidi edged him with 144.

And 800-metre Olympic queen Caster Semenya has the footballers comfortably beat after showing off her core strength.

The South African put together a mighty 176 reps in 45 seconds, a rate of 3.9 every second.
