Former Real Madrid president, Florentino Perez, has warned that Cristiano Ronaldo’s quit threat should not be taken lightly.
Ronaldo has apparently made an ‘irreversible’ decision to leave Madrid, after being accused of tax fraud worth £13m and has urged his agent Jorge Mendes to secure a return to Old Trafford.
Calderon, who brought the 32-year-old to the Santiago Bernabeu in 2009, said: “He is very strong-minded and when he decides something he goes through with it. The point now is whether he really has decided to leave.
“He likes Manchester United – that is something we all know. One year before he was going to come, he told me that he was really grateful to Manchester United, the fans, the people there, his teammates – everything in the city.”
Calderon also stated the Portugal captain will be irreplaceable and should not be sold for any price.
“It would be a big mistake if (president) Florentino Pérez doesn’t try to keep him with us.
“He has broken all the records at the club, he has got three Champions League in four years and La Liga this year. He has been a very important player.
“It took me a long time and a big effort to sign him when Manchester United didn’t want to let him go. We have to keep him.
“I think he will stay. I hope so. It would be very bad business to sell him.
“It doesn’t matter what we can get for him. There is no replacement for him. I don’t see anybody in world football who can substitute for him.
“I hope and wish he can stay with us until he retires,” he added.
