The Spanish midfielder feels the prolific attacker is in a class of his own, and believes his team-mate is not thinking about a transfer
Falcao has impressed in recent weeks with hat-tricks against Athletic Bilbao and Chelsea, and Gabi believes that many clubs would like to sign him if the opportunity arose.
"He is the best No.9 in the world and everybody wants to sign him," Gabi stated to AS.
"He's very high on confidence at the moment and always works hard. He has found his best style of play. Moving around and inside the area rather than dropping deep to collect the ball. His aerial power is brutal. He is the best header in the world, well ahead of everybody else.
"I spend a lot of time with him as he's my room-mate. He has a lot of ambition and he knows that he can achieve things here. He's happy to stay at Atletico and I can really see him staying put."
The 26-year-old is under contract with Atletico Madrid until the summer of 2016.
