Former Juventus and Germany star Jurgen Kohler has questioned Cristiano Ronaldo’s big game recordThe five-time Ballon d’Or winner ended his nine-year stay at Real Madrid for a move to Juventus this summer.However, he has yet to find the back of the net in his three Serie A appearances.And Kohler, who won one Scudetto, one Coppa Italia and the UEFA Cup at Juventus, questioned Ronaldo’s ability to perform in the biggest matches.The 33-year-old didn’t score in last season’s Champions League final and has never managed to find the net in a knockout match at a World Cup following Portugal’s last-16 exit at Russia.“There are no two opinions about Ronaldo’s qualities. He holds many records in Spain,” said Kohler, as stated on AS.“He has managed to win the major trophies. You have to pay tribute to him.“However, I must say that you rarely see Ronaldo in the decisive matches.Vidic: “Ronaldo is the most professional footballer I’ve seen” Andrew Smyth – September 14, 2019 Nemanja Vidic opened up on how a 21-year-old Cristiano Ronaldo’s professionalism left him stunned at Manchester United.“Then he goes on to score the goal to make it 4-1, with a penalty, and wants to be celebrated for it. But that’s the way he is, too.”Despite the criticism, Kohler did acknowledge Ronaldo as a “true champion” due to his outstanding work ethic.“I talked about him to a lot of people,” he said.“Everyone is fascinated because he also works a lot on the pitch.“Only the true champions are willing to work more. That applies to Ronaldo.“That’s the difference between world-class players and the regulars.”Kohler spent four years at Juventus and he also played for Cologne, Bayern Munich and Borussia Dortmund.The 52-year-old was also a part of the Germany squad that won the 1990 FIFA World Cup and the 1996 UEFA European Championship.
