Qatar team officials revealed Wednesday that star midfielder Hussain Yasser Elmohamadi stormed out of a training session Tuesday, reportedly in anger at having lost his place in the side to youngster Mohamed Al-Sayed.
The 28-year-old former Manchester City player, who currently plays for Egyptian giants Zamalek, did not feature in any of Qatar's group matches.
"I was expecting this question," said Bruno Metsu after being asked about Yasser at a press conference prior to his team's quarter-final match against Japan. "You have to be in the right state of mind, but if the players haven't got that kind of spirit, I think I have to kick them out."
"If they don't have the spirit, it's better for them to go," he added.
Team manager Abdulrahman Al-Mahmoud had previously told the Qatar Football Association website: "Yasser was removed because his response wasn't up to expectations and he was absent from some training sessions."
Qatar take on Japan at Doha's Al-Gharafa Stadium on Friday. Yasser is to play with Zamalek in their Friday Day 15 Egyptian Premier League match against El-Entag El-Harby.
