Former Manchester United striker Dimitar Berbatov is a free agent after his one-and-a-half year stay at French Ligue 1 club Monaco ended.
The 34-year-old Bulgarian joined from Fulham in January 2014 and scored in Monaco's Champions League win over Arsenal this season.
Berbatov was linked with a number of Premier League clubs in January.
Top-flight new boys Bournemouth have been reported to be interested this summer.
Vadim Vasilyev, Vice president of AS Monaco, said: "Dimitar Berbatov showed all his talent and a great professionalism. He is clearly among the greatest strikers who played for AS Monaco."
The striker, whose contract with the French club came to end this summer, scored 95 goals in 229 Premier League appearances for Tottenham, Manchester United and Fulham.
He hit the net nine times in 37 appearances for Monaco this season, as the Rouges et Blancs finished third in the league behind defending champions Paris St-Germain.
