Falcao is being linked with a January move to Real.
"He (Falcao) won't come in January but in June, who knows?" Perez said on television show Punto Pelota.
"Nothing is impossible and there is a lot of time between now and then, Falcao is a great player and I am aware that he wants to play for (Real) Madrid. I am aware of that, but it's normal. They told me."
Regarding Liverpool striker Luis Suarez, who was strongly linked with Real in the summer, Perez said: "Again, he is a great player, but we can't sign everyone."
