Radamel Falcao failed to quash rumours that he will make a big-money move to Real Madrid next summer when questioned about a possible move to the Bernabeu.
The Colombia striker only moved to Monaco in the summer, but earlier this week Real Madrid president Florentino Perez revealed his club could make a bid at the end of the season.
Perez also revealed he had told Falcao, who has scored seven goals in nine Ligue 1 appearances, of his interest.
While Falcao insists he is happy at Monaco, who paid Atletico Madrid a reported £50m for his service, he did not rule out the possibility of a return to Spain.
"All I can do is thank Florentino for his words but I have to respect my current club Monaco, who have made me feel very good and I am very happy," Falcao said at a promotional event in Bogota.
"It doesn't seem right to talk about Real Madrid's possible interest at the moment out of respect for the institution to which I am contracted to as of today."
Should Real Madrid wish to prise the 27-year-old away from Monaco they would be expected to match the fee that took him to France in the summer. Combined with the fees they paid for Gareth Bale (£86m) and Cristiano Ronaldo (£80m), the Spanish giants could end up with a front three costing in the region of £218m.
A move for Falcao could also dampen Reals interest in Liverpool striker Luis Suarez.
