Inter Milan vice-president Javier Zanetti is delighted with the impact of Lautaro Martinez.
The Argentina striker has been outstanding for the Nerazzurri this season.
Zanetti told TMW: "I am not surprised because we were convinced that he would prove his worth.
"He works with humility and is an important asset of the club. He is an investment that looks to the future. We are happy. I see him happy wearing the Inter shirt.
"Congratulations to all because they work with dedication. You see the spirit on the field."
On the prospect of moving for Udinese striker Rodrigo de Paul, he added: "He knows Italian football well, which has been on display in recent years. However, there is still a lot of time before the market and, out of respect for those who are already here, I prefer to say no more about the market."
