Barcelona held talks with the agent of Atletico Madrid star Sergio Aguero yesterday.
Arturo Calanes was at the Nou Camp for discussions with Barca officials, including sports director Txiki Beguiristain.
Along with Aguero, Canales also represents Barca player Gerard Pique and is in talks about adding Bojan Krkic to his client list.
In Argentina, El Mundo says Aguero confessed to reporters: "Hopefully, Leo (Messi) can take me (to Barcelona)."
Also on Calanes's books is Real Zaragoza striker Ander Herrera, who is a target for Barca and will have been mentioned during yesterday's meeting.
