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.
Asian champions Qatar enjoyed the backing of the 67,000-strong crowd Al Bayt Stadium, but could not follow a glitzy opening ceremony with a statement performance.
Ecuador thought they had made a dream start when Valencia headed in in the third minute, only for the goal to be ruled out by VAR for an offside in the build-up.
It was only a brief reprieve for Qatar, with Valencia putting the South American side ahead from the penalty spot in the 16th minute before doubling his tally just after the half-hour mark.
Qatar improved in the second period, but by the end of the 90 minutes the buzz of the opening ceremony was a distant memory.
“Our nerves betrayed us, we started really badly,” said Qatar coach Felix Sanchez. “We were unable to string together four passes in a row.”
Qatar will likely need to avoid defeat in their second Group A match against Senegal on Friday just to prevent the ignominy of becoming only the second hosts, after South Africa in 2010, to be dumped out in the first round.
Hopes were high among the crowd that Qatar could make a winning start, but the deficiencies of the World Cup debutants were ruthlessly exposed by an impressive Ecuador.
“It was a day we all dreamed of,” said Ecuador left-back Pervis Estupinan. “We are all very proud. We all know what an incredible captain we have with Enner Valencia.”
Qatar failed even to muster a shot on target in the game, with spectators filing out of the stands long before the final whistle.
