Atletico Madrid president Enrique Cerezo has angrily dismissed rumours that Radamel Falcao will leave the club in January.
Falcao has been in scintillating form so far this season and continued his purple patch with a brace in Colombia's 2-0 win over Paraguay last weekend.
The 26-year-old has been linked with a host of elite European clubs including Manchester City after Roberto Mancini was spotted watching the striker earlier this month.
Cerezo told reporters that he is fed up of discussing Falcao's future.
He said: "I'm not rude, but I'm really angry. Everything in life has a limit. I don't know his future, but if you know it you can tell him.
"I can't stand to hear this rumour anymore. I can only say that Falcao now plays for Atletico Madrid."
Falcao is level with star names Lionel Messi and Cristiano Ronaldo at the top of La Liga's scoring charts, with all three forwards scoring eight goals after seven league matches.
