The 23-year-old forward was seen by Barcelona as a potential replacement for Luis Suarez, who left the club to join Atletico Madrid during the summer, but he opted to stay at Inter instead.
Martinez's form has been pretty good this season, and whilst his tally of ten goals and five assists might not seem that impressive, he has been heavily rotated with Romelu Lukaku and Alexis Sanchez this season due to the large number of games played over the past few weeks.
He has always been the supplier to Romelu Lukaku as well, playing right behind the Belgian.
His form has led to him being linked with Barcelona once again this January, with them hoping for a move in the summer for the Argentine.
However, Italian news outlet Gazzetta dello Sport have reported that Martinez will sign a new contract at the club that is worth £86,500-a-week, decreasing his chances of leaving the San Siro.
Previously, the forward was on a £48,000-a-week deal, and he was in talks to get a new bumper deal with the club prior to the COVID-19 pandemic, but he was forced to lower his demands from the initial £140,000-a-week to the new value of £86,500-a-week.
What is most important for Inter is that through this new contract, they have removed the release clause that was big worry for them, wanting to keep him for the long-term as they hope to challenge current leaders AC Milan for top spot in Serie A.
