Qatar became the first host nation to lose an opening FIFA World Cup game when they suffered a 2-0 defeat to Ecuador on 20 November.Former Everton striker and Ecuador skipper Enner Valencia thought he had put his side in front in just the fifth minute.A terrible mistake by Qatar goalkeeper Saad Al Sheeb allowed Valencia to place home calmly, but VAR contentiously intervened and ruled that he was offside in the build-up.Valencia was on the scoresheet again in the 16th minute when the Fenerbahce forward was brought down in the box by Al Sheeb, with the referee pointing to the spot.He made no mistake as he fired his fifth FIFA World Cup goal for Ecuador, a record for any player of la Tricolor.Valencia grabbed Ecuador's second in the 30th minute with a fabulous header from the Fenerbahce frontman.An astute cross from Genk right-back Angelo Preciado found the Ecuador captain, who headed past Al Sheeb with aplomb.Qatar went desperately close to scoring their first-ever FIFA World Cup goal when Al-Duhail striker Almoez Ali should have nodded home from close range in the 45+5th minute.Ecuador were in total control throughout the first half, boasting 54% of possession.Renato Ibarra went close in the 55th minute after Qatar defender Bassam Al-Rawi gave the ball away to Los Angeles FC's Sebas Mendez.The Ecuadorian midfielder sent Ibarra on his way, but the forward was denied by a smart save from Al Sheeb.Qatar struggled to conjure up any threat against Gustavo Alfaro's well-drilled team.Brighton & Hove Albion forward Jeremy Sarmiento should have found the net in the 77th minute but sent his shot went high over the bar.Luckily for the Ecuadorian, he was ruled offside, much to his relief.Mohammed Muntari nearly got Qatar a goal in the 85th minute when Al Sheeb found him with a clever ball.The Qatari striker could only fire over the bar from a long distance.It's a first defeat for a host nation in an opening match at the FIFA World Cup and one that perhaps has people taking notice of Ecuador's talent.Here are some reactions from supporters on Twitter to the South Americans beating the hosts at the Al Bayt Stadium:Football Daily@footballdaily𝗘𝗖𝗨𝗔𝗗𝗢𝗥 𝗕𝗘𝗔𝗧 𝗧𝗛𝗘 𝗛𝗢𝗦𝗧𝗦 𝗤𝗔𝗧𝗔𝗥 #Qatar2022717𝗘𝗖𝗨𝗔𝗗𝗢𝗥 𝗕𝗘𝗔𝗧 𝗧𝗛𝗘 𝗛𝗢𝗦𝗧𝗦 𝗤𝗔𝗧𝗔𝗥 🇪🇨#Qatar2022 https://t.co/sEZBuLZuPzFenerbahçe SK@Fenerbahce @EnnerValencia14 #QatarWorldCup20228280113316😎 @EnnerValencia14 #QatarWorldCup2022 https://t.co/zIBZtnsf2y433@433Enner Valencia today:341443136Enner Valencia today: https://t.co/aHvZjshadNTroll Football@TrollFootball"F**k, I forgot to transfer $25m to Enner Valencia."499975780"F**k, I forgot to transfer $25m to Enner Valencia." https://t.co/9x2ac0bf3wZach Lowy@ZachLowyFor the third straight World Cup, a player has scored a brace in the tournament opener:2014: Neymar (71 minutes vs Croatia)2018: Denis Cheryshev (91 minutes vs Saudi Arabia)2022: Enner Valencia (31 minutes vs Qatar)26030For the third straight World Cup, a player has scored a brace in the tournament opener:2014: Neymar (71 minutes vs Croatia)2018: Denis Cheryshev (91 minutes vs Saudi Arabia)2022: Enner Valencia (31 minutes vs Qatar)Troll Football@TrollFootballThe referee team for the Qatar vs Ecuador game after disallowing the opening goal191553283The referee team for the Qatar vs Ecuador game after disallowing the opening goalhttps://t.co/FZY3TXl6H5World Cup Updates@wc22updatesVar rules out a perfectly fine goal by Ecuador3026607Var rules out a perfectly fine goal by Ecuador https://t.co/kyRR4GAMyrBilly@_billyreidI cashed out my Qatar 1-0 bet at £9.95 after seeing their first pass of the ball276862129I cashed out my Qatar 1-0 bet at £9.95 after seeing their first pass of the ball𝐀𝐅𝐂 𝐀𝐉𝐀𝐗 💎@TheEuropeanLad📸 - The official offside image released by VAR.9151603📸 - The official offside image released by VAR. https://t.co/ko4A28D7xHCasey Evans@Casey_Evans_Lol I think everyone's Golden Boot predictions probably forgot to include the three-goal headstart every striker is going to get playing against Qatar's keeper106487Lol I think everyone's Golden Boot predictions probably forgot to include the three-goal headstart every striker is going to get playing against Qatar's keeperSolyman Jami@JitokezeEcuador goalkeeper highlights vs Qatar82751Ecuador goalkeeper highlights vs Qatar https://t.co/4ELRB2RDaOJavier Lanza@javierlanzaLa hinchada #ECU ya tiene el primer hit del #FIFAWorldCup : “Queremos cerveza, queremos cerveza”78682659La hinchada #ECU ya tiene el primer hit del #FIFAWorldCup : “Queremos cerveza, queremos cerveza” https://t.co/Pk91fYLug5Alexei@MUFC_redarmy99The Ecuador goal against Qatar getting disallowed by VAR for literally no reason5382640The Ecuador goal against Qatar getting disallowed by VAR for literally no reason https://t.co/EIMDVTRITPgeorge@StokeyyG2What if Qatar just abandon the tournament if they don’t get through group stages…?455774What if Qatar just abandon the tournament if they don’t get through group stages…?THURSCERATO@thurzeera@StokeyyG2 Qatar are amazing!
