Iniesta and Ramos return for Spain
Long-term injuries kept Iniesta and Ramos out of last month's victories over Belgium and Estonia, when the European champions assured themselves of the top spot in Group Five and a place in the finals in South Africa next year.
Full back Alvaro Arbeloa misses out because of a knee complaint and Athletic Bilbao's Andoni Iraola was called up as a replacement, having made his international debut last year.
Spain will be looking to maintain their 100 percent record in the group when they take on bottom-placed Armenia in Yerevan on October 10. and second-placed Bosnia in Zenica four days later.
