Inter Milan vice-president Javier Zanetti has hailed the campaign of captain Lautaro Martinez.
Inter are eager to secure the striker to a new deal.
Zanetti told DAZN: “He is happy at Inter, as is his family. He demonstrates a great sense of belonging, he has held the role of captain in an exemplary manner. When Milito worked for Racing we followed him, I spoke to him often, Piero said he was very strong, he was 18-19 years old.
“He was surprised when he scored three goals in a match and he said he was happy with the goals, but not with his performance.
“If you answer like that, it means he has something that makes you think of course he was going to Atletico Madrid, one of his agents called me and told me that there were problems and that if we were still interested, we could talk about him. 'Immediately', I told him.
“They came to Milan, then Piero went to Argentina and finished it with Racing. He has improved every year, now he has reached a very important maturity and is a reference."
