Falcao scored back-to-back hat-tricks against Athletic Bilbao and Chelsea immediately prior to the international break, and then found the back of the net for Colombia in both their World Cup qualifiers against Uruguay and Chile.
Gimenez knows full well what he could come up against, saying: "Falcao is one of the best strikers in the world, he's in great form and one of Atletico's best chances of doing something great depends on him, even though they are a good team with great players.
"Falcao is another style of player, a pure centre-forward, a goalscorer.
"Obviously everyone talks a lot about (Lionel) Messi or Cristiano Ronaldo. Falcao is not at that level because he does less things, but in what he does he's the best."
