Iran made it through to the Round of 16 of the U17 World Cup with a hundred per cent record after beating Costa Rica 3-0 in their last Group C game at the Jawaharlal Nehru stadium in Goa, on Friday evening.
The Princes of Persia earlier defeated Guinea 3-1 and struck down Germany by a 4-0 scoreline, which means that Iran have scored 10 goals in all and conceded just once.
"Of course, we got nine points, but the most important thing is that we are in the next round. We must not forget the work that has gone in so that we get nine points. Scoring 10 and conceding just once shows that our schedule is in the right place," Chamanian said after the match.
However, asked if he sees his side as strong contenders, he responded, "No. Many teams are here and we must respect that."
Upon possibly missing his captain Mohammad Ghobeishavi, who was shown the second yellow of his tournament, the Iran coach chose to challenge the decision of referee Hamada Nampiandraza.
"I think the referee made a false decision of this card. So it is our request that the yellow card is cancelled," he said.
On the other side, Costa Rica coach Breansse Camacho has tipped Iran to do well in the youth competition.
"What we have seen from the Iranian side, I'm sure that they will go very far in the (U17) World Cup," he said.
Giving his thoughts on Friday's result, he commented, "We played against a very strong team tonight. We made mistakes in the first half and conceded two penalties. In the second half we tried to take some initiative but they (iran) made our life difficult in the game."
As they pack their bags, Camacho reflected, "Overall, I think we shouldn't have lost the match against Germany and against Guinea we played quite well a very physical team like Guinea."
