It was reported earlier this week that Cristiano Ronaldo recorded better results in the physical tests he carried out upon his return to Juventus than before Serie A stopped.So basically, Ronaldo is even better than he was before.Ronaldo’s Instagram page has the evidence to show he worked out non-stop during lockdown and Serie A might be in for a shock when the season resumes on June 20.The 35-year-old is already enjoying a fine campaign, scoring 25 goals in all competitions, but he’s still looking for that little bit more to add to his game.In a training session this week, Ronaldo was spotted wearing boots fitted with special studs designed to improve his speed and on-pitch performance.Ronaldo has attached rugby studs made by French company Smartpower to his boots, according to Tuttosport.

The Mirror report that Smartpower say their stud configuration improves acceleration and lateral stability, with each stud being interchangeable and moveable to suit the user.

Ronaldo hopes the longer, wider studs will enable him to grip the turf and run faster.

The Smartpower studs have already been used to great effect this season by Montpellier forward Andy Delort.

Delort has scored 12 goals and recorded the fastest running speed in Ligue 1, clocking a top speed of 36.8 km/h.

That's even faster than Kylian Mbappe.

Juventus have escalated their training sessions after recording a clean bill of health, meaning Ronaldo has been able to test the boots in group workouts.

"Yesterday the whole team underwent diagnostic tests, which came back with negative results," read a statement on the club's website last month.

"Juventus' training programme continues at Continassa. For several days now, the Juventus players have been carrying out individual training sessions in small groups, all whilst keeping their distance.

"In application of the indications by the FIGC’s [Italian Football Federation] Federal Medical Scientific Commission, yesterday, the whole team underwent diagnostic tests which came back with negative results; in the next few days training will resume in larger groups."
