The eighth competitive meeting is this one. Sociedad's only victory was a 1-0 upset at Old Trafford in September 2022 (due to a penalty kick from Brais Mendez), whereas United leads 3-2-1. United has a 2-1-0 record against Sociedad at home, having won 1-0 at Garnacho in 2022–23 and 4-0 at a technically neutral location in 2020–21. However, United lost that 2022 match. Sociedad has lost their last three trips to England (2-0 at Arsenal in 2003, 1-0 at United in 2022, and 3-0 at Sevilla in 2023—counting European ties) and has never defeated an English team away in Europe (D1, L4).

Ruben Amorim's Manchester United is a mixed bag. Following a 3-2 victory over Ipswich on February 27, they extended their winless streak to two games when they drew 1-1 at home against Arsenal in the Premier League on March 9 after Declan Rice cancelled out Bruno Fernandes' incredible free kick. They lead the league phase with 18 points and are undefeated (W5, D3) in the Europa League. They have drawn 1-1 with Twente this season and won three of their last four games at home in Europe (1-0 against PAOK, 2-0 against Bodo/Glimt, and 3-2 against Viktoria Plzen). In those four games, they have scored 11 goals (at a rate of 2.75 per game), but they have also given up three of them. Despite having a weakened roster due to injuries to Luke Shaw, Lisandro Martinez, Kobbie Mainoo, and Amad Diallo, they have won three consecutive EL home games.

Real Sociedad: La Real is having trouble. Their fourth loss in five games across all competitions (W1, D0, L4), including that 4-0 thrashing at Barcelona on March 2, came on March 9 when they lost 1-0 at home to Sevilla. They needed to defeat Midtjylland 7-3 in the playoffs to advance to this level after finishing 13th in the league phase of the Europa League (W4, D1, L3). They are 2-0-3 this season away in Europe, defeating PAOK (2-1) and Qarabag (3-0), but falling short against Lazio (2-1), Viktoria Plzen (2-1), and Anderlecht (2-1). They have scored in four of their five away EL games while giving up 1.8 goals per game.

Manchester United: Amorim's 3-4-3 thrives on attacking volume (18.8 shots per game) and possession (59.3% average in EL, highest in the competition). With Zirkzee (2 EL goals) and Rasmus Hojlund (5 EL goals) up top and Fernandes (10 EL goals, 10 assists lifetime) as the cornerstone, Alejandro Garnacho provides width. Midfield is strengthened by Casemiro's distribution (such as that outside-the-boot pass in the first leg) and Diogo Dalot's inverted runs. Matthijs de Ligt and Leny Yoro (doubtful, knock) have played good defence, but it's concerning that they've given up goals in 10 of their previous 11 home games in all competitions. With Chelsea on the horizon on March 16, they may rotate, but they will strive for victory.

Real Sociedad: Imanol Alguacil's 4-3-3 or 4-2-3-1 strategy depends on counterattacking speed and midfield dominance (52% EL possession). The assault is led by Oyarzabal (3 EL goals), Takefusa Kubo (2 goals), and Brais Mendez (2 goals), while Martin Zubimendi, who returned against Sevilla, anchors the midfield. They have given up 11 goals in their last five games across all competitions, including five in three away losses, indicating a lacklustre defensive performance. Kubo and Sheraldo Becker have returned, while Arsen Zakharyan (thigh) and Jon Pacheco (muscle) are sidelined. To survive, they will have to score, putting themselves at risk of being exposed to United's changes.

Old Trafford is a European stronghold; United has won 21 (75%), lost only once in their last 28 EL home games (against Athletic Club in March 2012). The odds are stacked against Sociedad because to their 0–1 record in England and their three consecutive away losses (against Lazio, Plzen, and Anderlecht) this season. Fernandes' big-game experience (such as against Arsenal) and United's attacking output (18.8 shots per game) could overwhelm Sociedad's poor defence (11 goals given up in 5 games). Although a close tie (1-1) is conceivable, a victory is more likely due to United's home advantage.

第八场比赛就是这一场。Sociedad唯一的胜利是2022年9月在老特拉福德1-0的逆转（由于Brais Mendez的点球），而曼联以3-2-1领先。曼联在主场对阵社会达的战绩是2胜1负，他们在2022-23赛季在加尔纳乔以1比0获胜，在2020-21赛季在技术中立的地点以4比0获胜。然而，曼联输掉了2022年的那场比赛。Sociedad最近三次造访英格兰都输掉了比赛（2003年客场2-0阿森纳，2022年客场1-0曼联，2023年客场3-0塞维利亚），并且从未在欧洲客场击败过英格兰球队（D1, L4）。

鲁本·阿莫里姆的曼联是一个大杂烩。继2月27日3-2战胜伊普斯维奇后，3月9日在主场1-1战平阿森纳后，他们将两场不败的纪录延长至两场。此前，德克兰·赖斯罚掉了布鲁诺·费尔南德斯的任意球。他们以18分领跑联赛阶段，并且在欧联杯中保持不败（W5, D3）。他们本赛季1-1战平特温特，最近4场在欧洲主场比赛中取得3场胜利（1-0 PAOK、2-0 Bodo/Glimt、3-2 victoria Plzen）。在这四场比赛中，他们进了11球（场均2.75球），但他们也丢了3球。尽管由于卢克·肖、利桑德罗·马丁内斯、科比·马努和阿马德·迪亚洛的伤病，他们的阵容有所削弱，但他们已经连续三场主场获胜。

皇家社会：皇马遇到麻烦了。3月9日，他们在主场0 - 1不敌塞维利亚，在各项赛事（W1、D0、L4）的5场比赛中输掉了第4场比赛，其中包括3月2日0 - 4大胜巴塞罗那的比赛。在欧联杯联赛阶段排名第13位（W4, D1, L3）之后，他们需要在季后赛中以7-3击败米德日兰才能晋级。他们本赛季在欧洲客场战胜了PAOK（2-1）和卡拉巴格（3-0），取得了2胜0负3负的成绩，但在对阵拉齐奥（2-1）、维多利亚·普勒岑（2-1）、安德莱赫特（2-1）的比赛中却落后于对手。他们在5场客场比赛中有4场进球，场均丢1.8个球。

曼联：阿莫里姆的3-4-3阵型在进攻量（场均18.8次射门）和控球率（英超平均59.3%，为欧冠最高）方面表现出色。齐尔克切（全场2粒进球）和霍伊隆德（全场5粒进球）位居榜首，费尔南德斯（全场10粒进球，10次助攻）是球队的基石，亚历杭德罗·加纳乔为球队提供了宽度。中场被卡塞米罗的分配（比如第一回合的外置传球）和迪奥戈·达洛特的倒转跑动所加强。德利特和约罗的防守很好，但令人担忧的是，他们在之前的11场主场比赛中有10场失球。随着3月16日切尔西的到来，他们可能会轮换，但他们会为胜利而努力。

皇家社会：伊曼纽尔·阿尔瓜西尔的4-3-3或4-2-3-1战术取决于反击速度和中场优势（52%控球率）。进攻由奥亚扎巴尔（3个进球）、久保武司（2个进球）、门德斯（2个进球）领衔，而在与塞维利亚的比赛中复出的祖比门迪则担任中场主力。在最近的5场比赛中，他们在各项赛事中丢了11个球，其中3场客场输球丢了5个球，这表明他们的防守表现乏术。久保和贝克尔已经回归，而扎哈里扬（大腿受伤）和帕切科（肌肉受伤）将缺阵。为了生存，他们必须进球，这将使他们自己面临暴露在曼联变化中的风险。

老特拉福德是欧洲的大本营；曼联在最近的28场主场比赛中取得了21胜（75%），只输了1场（2012年3月对阵竞技俱乐部）。由于本赛季他们在英格兰0胜1负的战绩以及客场3连败（分别对阵拉齐奥、普莱岑和安德莱赫特），所以赔率对Sociedad非常不利。费尔南德斯的大型比赛经验（比如对阵阿森纳）和曼联的进攻输出（场均18.8次射门）可能会压倒Sociedad糟糕的防守（5场比赛丢11球）。虽然平局（1比1）是可能的，但由于曼联的主场优势，胜利的可能性更大。
