Sporting CP are in advanced talks to sign Atletico Madrid striker Luciano Vietto.
Atletico chief Miguel Angel Gil Marin has confirmed a deal is close for the Argentine.
"We've reached a deal with Sporting for a loan with an option to buy, we are waiting for it to be accepted by the player," Gil Marin told Mega.
Vietto has previously acknowledged his "intention to leave on loan" to Atletico's sporting director Andrea Berta.
"But until all the players get back, we can't know," added the Italian.
