Clubs can still sign players whose contracts have expired even after the transfer window has ended. On June 30, Gomez's contract with Sevilla expired. He has been waiting to determine what to do next while also receiving attention from Saudi Arabia and France. The 35-year-old Argentine international played for Catania from 2010 to 2013 and Atalanta from September 2014 to January 2021. He spent the most of his career in Italy. After a disagreement with Atalanta coach Gian Piero Gasperini, he was traded to Sevilla. For La Dea, he made 252 competitive games, making 59 goals and 72 assists.
Monza had been associated with Gomez earlier in the season, but they decided to go forward when Gianluca Caprari suffered an anterior cruciate ligament injury that would keep him out for six months. The agreement will last through the conclusion of the current campaign.
