Ternana Calcio
On 21 August 2013, Avenatti signed a four-year deal with Italian Serie B side Ternana Calcio for €4 million, signing a four-year contract by his manager Paco Casal (which make him the most expensive purchase in the history of Ternana Calcio). He marked his first goal with rossoverdi in Series B on 17 November 2013 against Pescara. The first season at Ternana he played 25 appearances and 2 goals.
