After completing the signing of Antoine Griezmann, FC Barcelona are believed to have earmarked one of Lionel Messi's Argentina teammates, who has a release clause of €112m (R1.7 billion), as a possible transfer target.
The Blaugrana are believed to be in the market for a long-term replacement for striker Luis Suarez after being edged out by arch-rivals Real Madrid to the signing of Serbian forward Luka Jovic from Eintracht Frankfurt.
Ernesto Valverde's side has been heavily linked with a move for Paris Saint-Germain's wantaway star Neymar, but nothing concrete has come of their reported pursuit of the world's most expensive player.
As per Diario AS, the agent of Lautaro Martinez, who arguably outshone countryman Messi at the Copa America, has confirmed Barca's interest in his client, but revealed that no formal offer has been tabled.
"No one has called us but we know that there was a strong, important sounding and it is true that there is an interest on the part of Barcelona," agent Alberto Yaque said, as per Diario AS.
"He has exceeded expectations even to himself, but I was not surprised because I know of his quality."
Serie A giants Inter Milan are believed to have forked out €22.7 million (R220 million) for the 21-year-old, who signed a five-year deal after joining from Argentine outfit Racing Club in July 2018.
Should Martinez move to Barca, former club Racing would be entitled to 10% of the player's transfer fee.
The Argentina international made 35 appearances for the Nerazzurri last season, finding the back of the net on nine occasions.
