Iran's national team has begun training in Tehran this week ahead of their World Cup qualifier against Guam on Thursday.
Iranian team member Ramin Rezaian says Guam shouldn't be taken lightly.
"Guam have six points and is among the good teams in this group. We must take them seriously. If we don't, what happened in the match against Turkmenistan will repeat. We must begin the match seriously and play a game proper for Iran's dignity."
Iran drew with Turkmenistan 1-1 in the last round of matches.
Guam have started their World Cup qualifying with two wins in two games, including a 1-0 victory over Turkmenistan followed by a 2-1 victory at home to India.
