The Argentina midfielder struck in victory at Fiorentina yesterday.
The youngster signed for Como last summer from Real Madrid, which hold a buy-back option in the deal.
Transfer expert Nicolo Schira is reporting Como now want to negotiate the elimination of the clause.
He states: "Como are planning to try to delete Real Madrid’s buyback clause (€12m) for Nico Paz.
"Como want to keep him and would be ready to pay an important figure to lower the % on the future sale (currently is 50%) in addition to delete the buyback clause."
