CRISTIANO RONALDO showed off his ripped abs with his latest Instagram post.

The Al Nassr superstar posted a picture to his Instagram story of him working up a sweat in a sauna.

Ronaldo has maintained his stunning physique throughout his career.

And playing in Saudi Arabia has not altered his determination to keep fit.

Fans online took to social media to comment on the sauna pics, with one saying on Twitter: “Man’s discipline and dedication [is] on another level.”

A second added: “Man keep doing what he loves doing the most 🙌🏽♥️✊🏾.”

Ronaldo went over to the Middle Eastern country after signing a world-record £173million-a-year deal to sign with Al Nassr after his Manchester United contract was ripped up.

The Portuguese legend has scored 11 goals in 12 appearances since joining.

However, following a 0-0 draw with Al Feiha, Ronaldo struck a furious mood with an opponent.

A reported dressing room row between manager Rudi Garcia and the players followed.

Garcia has since been sacked, with Ronaldo reportedly critical of the Frenchman’s approach.

But now the former Real Madrid and Juventus star is trying his hand at directing with club chiefs said to be asking for his input on who the club should sign as their next manager.

Jose Mourinho and Zinedine Zidane are both reportedly on the club’s shortlist to succeed Garcia, while Under-19 coach Dinko Jelicic has been given the job on an interim basis.

And he will have a big ask with a crunch match against Al-Hilal coming up on Tuesday.
