Atalanta have signed Bosnia and Herzegovina defender Sead Kolasinac as a free agent, the Serie A club announced on Thursday.

Left-back Kolasinac, who has 53 international caps, arrives in Italy on a reported three-year deal after leaving Marseille at the end of last month.

The 30-year-old played 33 times in Ligue 1 last season, helping Marseille to third place and a spot in the Champions League qualifying rounds.

He previously won the FA Cup and two Community Shields at Arsenal, where he played 118 times over four-and-a-half seasons.
