The agent of Porto midfielder Fredy Guarin admits he has held informal discussions with Juventus regarding a switch to Italy.
Juve are expected to be busy during the January transfer window, with the club keen to bring in fresh faces to help them in their efforts to reclaim the Serie A title.
Guarin is among those on their radar, with the Colombia international considered to be a useful addition.
No contact has been made as yet with Porto, but Juve have sounded out the possibility of a move with the 25-year-old's representative.
"With the Bianconeri there are the beginnings of negotiations, but nothing official," Marcelo Ferreyra told calciomercato.com.
"We are still at the stage of information exchange.
"At the moment their officials have only talked with us and not with Porto.
"Other requests? At the moment Fredy is only wanted in Italy. It is still difficult to say whether he will leave in January.
"A valuation of €11million (£9.1m)? That could be right, but that is a matter for the two clubs to discuss."
