Iran coach Branko Ivankovic expects to have a fully-fit squad to select from for his side's World Cup opener against Mexico on June 11.

Key midfielder Mehdi Mahdavikia has been struggling with a thigh injury since last week's 2-2 draw against Croatia and has been receiving treatment from world renowned sports injury specialist Hans-Wilhelm Mueller-Wohlfahrt.

Mahdavikia now expects to return to training on Tuesday and to line up against Mexico in Nuremberg.

Ivankovic said: "Such an injury needs a little time for recovery, but Mahdavikia is a fighter and he will be ready for the first match. Everyone will be ready for Mexico on June 11."

One player not currently training with the rest of the Iran squad is defender Yahya Golmohammadi, whose departure to Germany was delayed by passport problems.
