Manchester United’s four-match winning run came to a crashing halt as Real Sociedad won 1-0 at Old Trafford. A controversial penalty handed the Red Devils their first Europa League loss on home soil in 19 matches.A solemn atmosphere had gripped the stadium, with a much-changed United outfit struggling for fluency in possession, creating precious little as result. Anthony Elanga’s searing pace on the left created a couple of openings, but the end product couldn’t be found. Imanol Alguacil’s men enjoyed more of the ball than the hosts, and arguably had the best opening of the half when Brais Méndez’s snapshot drifted narrowly wide of David de Gea’s goal.EUROPA LEAGUE: Arsenal manage to diss the sturdy Swiss, Roma stumble in BulgariaCristiano Ronaldo, making his first Europa League appearance in two decades, had the ball in the net before the interval, but his powerful header was ruled out for offside. The legendary striker had a chance to put his side ahead after the break, but failed to meet Bruno Fernandes’ cross with any conviction – a huge chance wasted by his lofty standards.The Red Devils’ wastefulness nearly came back to haunt them when half-time substitute Alexander Sørloth met a pinpoint cross from the left, but the Norwegian fired his header over. The visitors’ growing momentum would pay dividends as they took the lead before the hour mark in controversial circumstances. Lisandro Martínez was penalised for blocking a shot with his arm, despite the fact it rebounded off his leg first, and Méndez converted to stun the home crowd.Erik ten Hag’s men needed to respond but were desperately struggling to create against a staunch Sociedad rearguard. Casemiro’s effort from range tested Álex Remiro, but the hosts ran out of ideas and lost for the fifth time in the last 11 meetings with Spanish sides in this competition. Meanwhile, Sociedad won for just the second time on the road in their last eight Europa League away trips, scoring and beating United for the first time ever.Elsewhere, Lazio began their assault on this season’s Europa League with an emphatic 4-2 mauling of in-form Feyenoord at the Stadio Olimpico.Feyenoord’s unbeaten Eredivisie form this season is in stark contrast to their Europa League fortunes, winning only once in their last 12 fixtures on the road in the competition and the clock had barely reached the third minute before Lazio were ahead. A sodden Stadio Olimpico pitch didn’t restrict some neat interplay 25 yards from goal with Matías Vecino applying a deft, outside of the boot through ball for Luis Alberto to finish clinically and give the hosts an early lead.The Dutch club’s solid start to the season has been made all the more impressive by the fact that Arne Slot’s side has been decimated by losing a number of key players in the summer. Cyriel Dessers, Tyrell Malacia, Luis Sinisterra and Marcos Senesi, who all played key roles in their run to the Europa Conference League final, have moved on, but their domestic form has seemingly masked the problems which were expertly exploited by Lazio in the early exchanges. Felipe Anderson doubled the home side’s lead just 10 minutes later with the Brazilian cutting in from the right before beating Justin Bijlow at his near post from 18 yards out.Maurizio Sarri’s men were rampant and added a third on 28 minutes. This time, Vecino transformed from provider to predator, stabbing home a rebound from close range after Bijlow had denied Mattia Zaccagni.Feyenoord came out for the second half with a modicum of extra intent but if there was any lingering doubt, any glimmer of hope for the Dutch side, Vecino put that to bed after Luis Alberto cut open the defence once again with an incisive through ball and the Uruguayan scored his second of the night with a smart finish. Santiago Giménez converted a penalty for the visitors on 69 minutes before adding another goal late on but the game was well won by then making the substitute’s double little more than a consolation. Lazio have played the most games of any side yet to win the Europa League but look in prime form to correct that this season.UEFA EUROPA LEAGUEThursdayFC Zürich – Arsenal 1-2 (1-1)/Kryeziu 44 pen – Marquinhos 17, Nketiah 62/PSV Eindhoven – Bodø/Glimt 1-1 (0-1)/Gakpo 63 – Gronbaek 44/AEK Larnaca – Stade Rennais 1-2 (1-1)/Oier 33 – Theate 29, Assignon 90+4/Fenerbahçe – Dynamo Kyiv 2-1 (1-0)/Gustavo Henrique 35, Batshuayi 90+3 – Tsygankov 64/HJK – Real Betis Balompié 0-2 (0-1)/Willian Jose 45+2, 64/Ludogorets Razgrad – Roma 2-1 (0-0)/Cauly 72, Nonato 88 – Shomurodov 86/FC Union Berlin – Royale Union Saint-Gilloise 0-1 (0-1)/Lynen 39/Malmö FF – Sporting Braga 0-2 (0-1)/Bruno Rodrigues 30, Horta 70 pen/Manchester United – Real Sociedad 0-1 (0-0)/Mendez 58 pen/Omonia Nicosia – FC Sheriff Tiraspol 0-3 (0-1)/Akanbi 2, Atiemwen 54 pen, Diop 76/Lazio – Feyenoord 4-2 (3-0)/Luis Alberto 4, Felipe Anderson 15, Vecino 28, 63 – Gimenez 69 pen, Idrissi 88/SK Sturm Graz – FC Midtjylland 1-0 (1-0)/Emegha 8/FC Nantes – Olympiacos 2-1 (1-0)/Mostafa Mohamed 32, Guessand 90+3 – Moutoussamy 51 og/SC Freiburg – Qarabağ FK 2-1 (2-1)/Grifo 7, Doan 15 – Vesovic 39/FK Crvena zvezda – AS Monaco 0-1 (0-0)/Embolo 74 pen/Ferencvárosi TC – Trabzonspor 3-2 (3-1)/Nguen 5, 44 pen, Traore 29 – Gomez 40, Bozok 72/***odds are subject to change©FlashScore
