The midfielder from Porto is one of the few players from the Colombian National Team who has not yet confirmed where he will play in the 2015-2016 season.
Rumors of his departure from Porto and his possible destinations started in May. First it was Spain (Atletico Madrid) and then Brazil (Flamengo, Cruzeiro, and Atletico Mineiro inquired about him).
Last week, Italian media reported his transfer to Bologna for 19 million euros, but negotiations have stalled in recent days.
Genoa and Palermo, also from Serie A, have appeared on the radar, but according to Sky Sport journalist Gianluca Di Marzio, the most likely option is Sampdoria.
The sports reporter affirmed on his website that club officials had a meeting with the player's agent, Ricardo Calleri, to begin studying the possible agreement.
If the transfer is completed, Quintero would be a teammate of his compatriot and national team companion, Luis Fernando Muriel.
