However, with an exit beginning to look unlikely, the striker has been given a new squad number for the 2019-20 Serie A season, which starts this weekend.
Icardi was told to look for a new club by chief executive Giuseppe Marotta in July and was excluded from the club's pre-season tour of Asia.
The 26-year-old, who was stripped of the club captaincy last season, was tipped to move to Juventus in a part-exchange deal involving Paulo Dybala, but no such agreement has been reached.
Most recently, he was linked with Ligue 1 side Monaco, only for wife and agent Wanda Nara to rule out such a transfer.
Nara seemed to hint at Icardi staying at Inter with a tweet on Friday showing her photographed with other wives and girlfriends of Nerazzurri players, captioned 'another year together'.
Antonio Conte's side begin their Serie A season at home to Lecce on Monday.
