CRISTIANO RONALDO has showed off his ridiculously expensive watch – but it still only cost the Al-Nassr ace a tiny portion of his huge wealth.

The 38-year-old became the highest earning sportsperson in the world when he made his high-profile switch to Saudi Arabia at the end of last year.

He makes an estimated £173m a year from his wages and commercial activities at Al-Nassr.

It is safe to say Ronaldo is making use of his spare change as he showed off a beautiful watch on Instagram.

The star poses in a stylish polo shirt and grips a white mug on his Instagram story.

But eyes were quickly drawn to the object on his wrist – a £750,000-valued watch from Jacob & Co.

The dazzling device immediately draws attention with its blue colour scheme and majestic design.

It would have cost Ronaldo a pretty penny but the forward has more than enough in the bank after more than a decade of being one of the planet’s biggest sporting stars.

He is the most popular athlete online with a combined 855million social media followers and makes an estimated £3.3m-a-week.

And all of that attention brings commercial opportunities which props up his already huge wage packets.

The move to Al Nassr helped Ronaldo pip his old rival Lionel Messi to the top of Forbes 50 best-paid athletes list.

The former Manchester United superstar leapt from third in last year’s list to top after sealing his eye-wateringly lucrative move.

Kylian Mbappe follows his PSG team-mate Messi in third place, ahead of basketball legend LeBron James.

Boxing star Canelo Alvarez follows in fifth before the golf pair of Dustin Johnson and Phil Mickelson.

NBA stars Stephen Curry and Kevin Durant came 8th and 10th, sandwiching tennis great Roger Federer.
