These are the 2013-14 season AEK Athens shirts by Puma.
AEK were relegated last season and elected to self-demote further and play in the top Greek amateur division to try to deal with financial issues. They will wear these shirts - one gold and one black - with interchangeable black and gold shorts and socks.
