Italian - Nigerian defender Angelo Ogbonna, 24, will have hernia surgery in the coming days and this will keep him on the sidelines for at least 40 days if there are no complications, writes Turin based sports daily TuttoSport.

It was decided after Sunday's 2 - 4 home loss to AC Milan that the Italian internationalist will undergo the knife because of the injury.

Ogbonna has played 12 games in the Serie A this season, and lasted the entire duration in each of the games.

According to reports, the Torino ace is on the wishlist of AC Milan, Roma, Juventus and Manchester United in the winter transfer market.
