The 25-year-old has made more than 100 appearances for the Rossazzurri since signing from San Lorenzo in the summer of 2010.
The winger has notched eight goals in 35 appearances so far this season, helping the Sicilian club up to eighth place in Serie A with just one game remaining.
His displays have caught the eye of rival clubs, with Pulvirenti revealing he has received a number of bids.
However, it appears the Argentine will be playing his football at the Vicente Calderon next season after it was confirmed Atletico are close to sealing a deal.
"The negotiations with Atletico Madrid are very advanced, we have some serious bids. I think Gomez will go there," said Pulvirenti.
"How we'll replace Gomez? We have [Lucas] Castro and we have already taken [Sebastian] Leto.
"We will also continue to work in Argentina where there are many players that familiarise themselves very well in Serie A."
