Dejagah is without a team since parting company with Wolfsburg in early June.
“I traveled to Doha to see my friends. I’ve played in Al Arabi for three years but at the moment I’d rather play in a European team,” Dejagah said.
“The 2018 World Cup is a great goal for me and I want to make sure I am fully prepared for the competition,” he added.
Dejagah played for Team Melli in the 2014 World Cup.
