Imminent Chelsea signing Radamel Falcao had a say in Jackson Martinez's decision to join Atletico Madrid.
The Porto striker has announced he's chosen Atletico ahead of Arsenal and AC Milan.
Asked about conversations with Colombia team-mate Falcao, who enjoyed his best spell at the Vicente Calderon, Martinez said: "Yes, I got the best references.
"At Atletico [Falcao] was a leader and I came to Porto after him and I was fine, I hope the same thing happens here."
