In a midfield-heavy squad, Koumantarakis is just one of three forwards selected by Jomo Sono.
He had been on the outskirts of the squad but showed his determination to be selected by missing the Swiss Cup final in a bid to make it to Korea and Japan.
A lanky striker, he was the top scorer in the league in the 2001/2002 season.
He was initially a surprise inclusion when called up for the 30-man provisional squad, but did enough to get the nod ahead of Bradley August.
