Iran's FIFA World Cup campaign has been rocked by the departure of assistant coach Majid Salih.
As reported by TeamMelli.com, Salih was sitting in the stands - and not alongside head coach Carlos Queiroz - for one of Iran's friendlies at their training camp in Austria, fuelling speculation of unrest.
Salih tendered his resignation when the team returned to Iran, and becomes the second assistant after Omid Namazi to leave under Queiroz's reign this year.
Iran's football federation chief Ali Kaffashian reportedly sought to recruit Salih to have an Irani presence in the coaching group, alongside Portuguese boss Queiroz.
The shock resignation comes less than two weeks before Iran's World Cup opener against Nigeria in Curitiba on June 16.
