Cristiano Ronaldo puts in final touches before Real Madrid's Champions League showdown with Juventus as he works out muscular legs in the gym

• Real Madrid star Cristiano Ronaldo shows off huge quads as he works in the gym
• The Portuguese claimed to be putting in the 'final touches' ahead of Saturday
• Real Madrid are looking to retain the Champions League title against Juventus

Cristiano Ronaldo is making sure he is in tip-top shape for Real Madrid ahead of their Champions League final against Juventus, showing off his incredibly muscular quadriceps in his latest gym picture on Instagram.

The 32-year-old has not played since May 21, when Real Madrid sealed the title with a 2-0 win over Malaga. On Saturday, Real will attempt to become the first team to retain the Champions League in the modern era in Cardiff.

In the meantime, Ronaldo is making sure he doesn't lose any of his incredible strength, hitting the gym to put in some 'final touches' in ahead of the crunch clash against the Italian champions.

It was certainly a different scene to the one his Real Madrid team-mate and captain Sergio Ramos was enjoying on Wednesday. 

The centre-back was pictured living the high life on a yacht off the coast of Ibiza, and was joined by fellow Real Madrid stars Luka Modric, Lucas Vazquez, Keylor Navas and Mateo Kovacic.

But it is the hard work in the gym that has always set Ronaldo aside from the rest, helping him to transform him from a skinny teenager at Sporting Lisbon to the Adonis that we see today. 

There is unlikely to be any doubt over the commitment of Ramos and Co, however. After all, the Spaniard's incredible form this season has allowed Real Madrid to win their first La Liga title since 2012.

Soon, they will all be on a flight to the less sunny setting that is the Welsh capital city. The Principality Stadium plays host to this year's final, which will be played under a closed roof for the first time in its history.

They face Juventus, who are contesting their second Champions League final in just three seasons and are also looking to complete the first treble in their history after sealing Serie A and the Coppa Italia last month.
