Qatar became the first home team to lose their opening World Cup match as Ecuador cruised to a 2-0 victory over the hosts, with Enner Valencia scoring twice in the tournament curtain-raiser on Sunday.
Asian champions Qatar enjoyed the backing of the majority of the crowd at the 60,000-capacity Al Bayt Stadium, but could not follow a glitzy opening ceremony with a statement performance.
Ecuador thought they had made a dream start when they silenced the home fans as Valencia headed in, only for the goal to be ruled out by VAR for an offside in the build-up.
Valencia did break the deadlock with a penalty in the 16th minute and doubled his tally just after the half-hour mark.
Qatar improved slightly in the second period, but by the end of the 90 minutes, the excitement which greeted the build-up - featuring Morgan Freeman and BTS star Jung Kook - was a distant memory as thousands of fans left early amid a deflated atmosphere.
Felix Sanchez’s Qatar will likely need a positive result in their second Group A match against Senegal on Friday just to avoid the ignominy of becoming only the second hosts, after South Africa in 2010, to be dumped out in the first round.
