The French defender is now a free agent after mutually terminating his contract with RB Salzburg.
Transfer expert Fabrizio Romano is reporting a deal between Udinese and Solet is now being settled.
However, Solet will only be able to train with Udinese before he can formally register with the Zebrette on January 1, 2025.
The 24 year-old was discussing a move to the Saudi Pro League before Udinese's intervention.
