Iran boss Branko Ivankovic wants to lead the nation to the second round for the first time after announcing a 23-man squad for the tournament.
Branko Ivankovic has big ambitions at this year's tournament
The Croatian coach has set his sights on upsetting one of seeded teams Mexico and Portugal in group D.
He said: "I'm completely aware of the tough job we have in Germany. But I have enough reliable players."
The biggest surprise was the selection of Saipa midfielder Masoud Shojaee, tipped for great things by Ivankovic.
The Middle East nation's coach worked as an assistant to Miroslav Blazevic when he led Croatia to third place at the 1998 World Cup in France.
Under Blazevic, the Iranians narrowly missed out on qualifying for the 2002 finals - losing in a two-legged playoff to the Republic of Ireland.
Ivankovic's squad features veteran striker Ali Daei, who will be playing in his second World Cup after appearing in France eight years ago.
There are also five Europe-based players selected, including Bayern Munich's former Asian Player of the Year Ali Karimi.
