The Argentina and Spurs center half is now seen as one of the best in his position in the world.
Per Argentine journalist Gaston Edul, Manchester United, Paris Saint-Germain and Real Madrid all came knocking.
However, Spurs rejected any approach for Romero, as he is a cornerstone of their team.
Alongside Micky van de Ven, he is the sort of rapid center half that manager Ange Postecoglou admires.
Edul’s social media post translates to: "Cristian Romero has the interest of three teams in this transfer market: Manchester United, PSG and Real Madrid.
"Tottenham responded that they would not sell him. He is essential for Postecoglou. They did not even put a price on him.
"He will have offers again in the next transfer market when Romero only has two years left on his contract."
