Bologna have announced the signing of Chile international Gary Medel, who joins the club from Besiktas.

The midfielder secures a return to Serie A two years after he ended a spell with Inter to move to Turkey.

Medel trained for the first time with Bologna on Thursday, with coach Sinisa Mihajlovic taking the session despite his ongoing treatment for leukaemia.

He goes straight into the Bologna squad for Friday's home game with SPAL after the club announced his signing with an amusing social media video referencing his 'Pitbull' nickname.

Medel, 32, was sent off during the Copa America after a clash with Argentina superstar Lionel Messi.

He has twice won the Copa America with Chile, who claimed glory in the tournament in both 2015 and 2016.
