Trezeguet returns to join Mohamed Salah and Mohamed Elneny in Egypt squad.
Aston Villa's Trezeguet has been named in Egypt's final 25-man squad for the Africa Cup of Nations despite not playing since April.
On 6 December he continued his recovery from injury as he played and scored for Aston Villa's under-23 side and since then he has been an unused substitute for the first team for their past three games.
As expected Egypt coach Carlos Queiroz also included Liverpool's Mohamed Salah, who is set to captain the team, and Arsenal's Mohamed Elneny for the tournament that begins on 9 January in Cameroon.
The other three overseas-based players in the former Manchester United assistant manager's squad are Ahmed Hegazi (Saudi Arabia), Mostafa Mohamed (Turkey) and Omar Marmoush (Germany).
The record seven-time winners begin their campaign on 11 January against Nigeria, before playing Guinea-Bissau and finally Sudan.
