Katia Aveiro, sister of Manchester United star Cristaino Ronaldo has fired back at Real Madrid President Florentino Perez after his brutal response over the possibility of re-signing the Portugal international.

When asked if he would re-sign Ronaldo, who is the club’s record goalscorer with 451 goals, he replied: “Again? He’s 38-years-old!”

And Ronaldo’s sister, Katia hit back at Perez’s comments by defending her brother.

On Instagram, Katia Aveiro said: “He’s 38 years old but he can jump two metres high in the air and stay in it for three minutes and his body has no fat.”

Ronaldo, who is actually 37, is keen to leave Manchester United this summer, but has struggled to attract offers from top European sides with the Portuguese star desperate to play in the Champions League.
