Mustafa Amini has angrily rejected Young Socceroos coach Paul Okon's claims that he was not fit enough to play at the Fifa Under-20 World Cup in Turkey.
Okon announced his 23-man squad for the youth tournament last week, surprisingly opting not to give Amini, who is widely considered one of Australia's most exciting up-and-coming players, a ticket to Turkey.
Amini was part of the Young Socceroos' training camp in Europe from May 20-31, playing in warm-up matches versus the Netherlands and Germany.
But he was left out of the final squad, with Okon telling the 20-year-old former Central Coast Mariners midfielder that his fitness was not up to scratch.
Having had time to reflect on Okon's decision, Borussia Dortmund prospect Amini still does not understand the coach's ruling.
"My fitness is fine," Amini told SBS.
"I played 81 minutes of our match against the Netherlands Under 21s and I think I was one of our better players.
"I got 40 minutes in our 2-2 draw against Germany and I was dreaming about being a part of our World Cup campaign.
"I put off my holidays to be a part of this and I am really disappointed and surprised not to have been picked."
Amini blamed a blood test for not being selected by Okon, which he believes was affected by his trip to Wembley for the UEFA Champions League final on May 25, midway through the Young Socceroos' European tour.
"I had a blood test after not sleeping for the best part of two days following the Holland match, because I was part of the Dortmund party which went to Wembley for the European Champions League final the next day, and it was full on for 48 hours," Amini said.
"Then I flew to Cyprus [to link up with the Young Socceroos] and had the test.
"Of course after not sleeping for two days my blood won't be the same as everybody else's and that was the excuse I was given.
"Paul Okon also mentioned my skin fold tests but I am an on different program at Dortmund where you bulk up then you trim down afterwards.
"I proved my fitness in that Holland game.
"We had a week in Cyprus after that and I did well when I came on against Germany, so fitness-wise there were no issues at all."
Amini went to the 2011 Under-20 World Cup in Colombia with the Young Socceroos, starting two games and coming off the bench in the other as Australia failed to get out of their group.
The playmaker with the distinctive red afro was overlooked by Okon again on Tuesday when the Young Socceroos head coach named Sydney FC youngster Hagi Gligor as a replacement for Terry Antonis, who tore his quad in Australia's final warm-up match against New Zealand on Monday.
