Inter Milan coach Antonio Conte admits Lautaro Martinez has the potential to be world class.
However, Conte says the Argentina striker needs to decide if he's willing to make the needed sacrifices to reach the elite level.
He explained: "Lautaro must work, must work and that's it. He shouldn't think that the goal is everything for a striker, because for me it is not like that.
"He must work for the team, he is growing a lot, he is becoming a complete striker. We like when he gives assists and when he's scoring.
"He has a lot to improve, he has important potential, it's up to him to decide if he wants to become a top player or if he wants to stay as a mid-level player."
