The 37-year-old Manchester United star and his 'boy' Cristiano Ronaldo Jr stood outside the room, as they geared up to plunge their bodies into freezing temperatures for their cryotherapy session, which eases muscle pain.

Sharing the photo on Instagram and Twitter, the Portuguese superstar wrote, "Recovery time with my boy," along with an ice block emoji. The father-son duo wore underwear from Cristiano's CR7 men's and boy's range, with the star's son wearing a pair of black gloves before heading into the chamber. Fans gushed over the father-son photograph, with several hailing the two and 'Present and Future'.

Last month, Ronaldo Jr copied his father's iconic 'Siuuu' celebration while playing for United's under-12s, which got several supporters demanding the 11-year-old be handed over a number '7' jersey.

Ronaldo's son was born in San Diego, California, in 2010, when he announced he would be caring for him under his exclusive guardianship while his mother decided to keep her identity confidential.

It comes after the Portugal international and his partner Georgina Rodriguez revealed earlier this month that the name of their newborn daughter is Bella Esmeralda.

The 28-year-old announced the name they had picked alongside three adorable photos which saw the little one sleeping in her cot, days after confirming the child's twin brother tragically died at birth.
