The Serbian coach dropped four players from his 27-man roster with Girona defender Jonas Ramalho being one of the biggest omissions.
Ramalho was part of the Spanish under-19 squads which won the European Championship in 2011 and 2012.
The 26-year old whose father is from Angola was called up in the build-up to the tournament in Egypt but he failed to make the final selection.
The defender who had 38 appearances for his Italian club across all competitions last season is one of the surviving members of Agnola’s 2013 Afcon squad.
Palancas Negras are in Group E, with Mauritania, Mali and Tunisia. They would begin their campaign on June 24 against the Carthage Eagles before taking on Mauritania on June 29 and then the Eagles of Mali on July 2.
