Real madrid selling cristiano ronaldo to juventus is historic error says calderon

I think there may be some confusion here!

Cristiano Ronaldo did not play for Real Madrid and then get sold to Juventus. In fact, Cristiano Ronaldo played for Manchester United from 2003 to 2009, before joining Real Madrid in 2009. He played for Real Madrid from 2009 to 2018, winning numerous titles and individual awards, including five Ballon d'Or awards.

In 2018, Cristiano Ronaldo left Real Madrid to join Juventus in a transfer worth €100 million. This move was a significant one in the world of football, as it marked the first time a player of Ronaldo's caliber had left Real Madrid for another club.

So, it's not possible for Calderon to say that Real Madrid selling Cristiano Ronaldo to Juventus was a "historic error", as this move was a deliberate and highly publicized transfer that took place in 2018.
