- Douglas Costa is stunned by Ronaldo's work rate in Turin
- The 33-year-old joined the Old Lady this summer after ending his nine year reign with Real Madrid
- He is the most successful player in the history of Champions League with five UCL titles in his career
Brazil forward Douglas Costa says he has never seen a player as hard working as Juventus new signing Cristiano Ronaldo.
The Portuguese superstar joined the Old Lady in a four year deal around £105.30 million from Real Madrid this last month.
Before ending his nine year reign with Los Blancos, he helped them win four Champions League titles among other domestic and European silverware.
However, despite missing out of his new club's preseason tour in the United States, Ronaldo has been getting adequate preparation ahead of the new season.
The 33-year-old started training with the rest of the team that were left out of the tour after his return from his China trip.
And the Brazilian forward has no word to describe the quality of the five time Champions League winner Ronaldo.
Costa said he commences training before the rest of the squad and still continues after everyone was done: "It's impossible to follow Cristiano Ronaldo at training.
"When we arrive, he's already training and when we leave he's still training. I've never seen a player like that." Douglas Costa said.
Ronaldo is scheduled to make his debut for the Italian champions in their Serie A opener against Chievo Verona later this month.
Before moving to Spain, Ronaldo had featured for both Manchester United and Sporting CP, while his move to the Italian League at his present age has got so many people talking.
NAIJ.com previously reported that Juventus mega signing Cristiano Ronaldo trained for the first time with his new teammates on Tuesday.
The Portuguese superstar joined the Old Lady in a four year deal valued at £99 million summer move from Real Madrid this summer, as he was put through a pre-season physical.
He spent nine seasons at the Santiago Bernabeu and won a total of 16 major titles - four of which were Champions Leagues.
