Benevento made Kamil Glik their first signing since the promotion and President Oreste Vigorito has reportedly planned to bolster the attack with either Daniel Sturridge or Graziano Pellè.
The arrival of the former Torino and Monaco defender was confirmed after a successful medical visit at Villa Stuart in Rome.
“I’m very happy, I have missed Italy,” Glik said, according to Sky Sport Italia journalist Gianluca Di Marzio.
