After a season training in Quilmes without playing, Iturbe has returned to Paraguayan capital Asuncion to train with Cerro Porteno, the team which still holds his playing rights and where he will appear until he can officially transfer to Porto in June, when he turns 18.
The player, dubbed 'La Pulguita' in Argentina for his similar playing style to Lionel Messi, fell out with Cerro and the Paraguayan FA last year in a bitter contract dispute, and despite the temporary switch back to the country in which he was raised the youngster insisted that his future is with the Albiceleste.
"This is a decision that I took as soon as I first put on the Argentina shirt. Paraguay is now a closed chapter in my life," Iturbe told Radio Monumental from Asuncion.
The talented playmaker moved on to refer to the dispute which marred his 2010, and blasted the Paraguay directors for what they put him through.
"I suffered a lot. When I most needed their help, [the FA] were not there for me. In Argentina on the other hand I was brilliantly looked-after. I am very grateful and I cannot go back."
Iturbe was born in Buenos Aires to Paraguayan parents, and moved to Paraguay at an early age but with dual nationality for both the South American nations. After representing the Guaranis at youth level the 17-year-old switched to Argentina in 2010, and confirmed his status as one of football's most promising prospects with a brilliant strike against Chile and a match-winning effort against Brazil.
