Lionel Messi won the 2019 Ballon d'Or for the record sixth time. Second to him was van Dijk, while Ronaldo finished on the third spot.
Notably, Ronaldo gave the ceremony a miss. And, at the event, when a journalist asked the Liverpool defender if Ronaldo's absence meant that he had one less rival, he cheekily responded, "Was he a rival?"
Katia started off by pulling van Dijk's leg for playing in England and reminded him that her brother was a three-time champion there, while the former is yet to lay his hand on the title despite playing for years.
"Ronaldo was even the best player and best scorer in the country where you play. He was even younger than you," she wrote.
Katia reminded van Dijk of Liverpool's defeat to Madrid
"He was at Real Madrid. Does that tell you anything? Because this club, with this Cristiano, even beat you in the Champions League final. And yeah, of these Ballons d'Or, Ronaldo already has five," Katia added.
