Slovenia international Valter Birsa is a free agent after terminating his contract with Cagliari by mutual consent.
The 34-year-old first joined Cagliari in January 2019 and had been under contract until June 2021.
He was frozen out of the squad this summer and did not play a single game in 2020-21.
Following negotiations that dragged on for weeks, Birsa has finally managed to agree a contract termination that suits all parties.
Birsa made 28 appearances for the Sardinians.
His previous clubs include Genoa, Torino, Milan and Chievo.
