Two teams still searching for their first victory of the new campaign meet at the London Stadium on Friday night, as West Ham United host Chelsea in the Premier League. Both endured frustrating opening weekends, with the Hammers humbled at Sunderland and Chelsea unable to break down Crystal Palace at home.

West Ham’s opener could hardly have gone worse. A 3-0 defeat at the Stadium of Light exposed frailties across the pitch and left supporters questioning Graham Potter’s approach. The manager is already under scrutiny after failing to inspire confidence since his arrival midway through last season, and the pressure only grows after such a poor start. Having won just one of their final eight home league matches last term, the Hammers know they must improve quickly to ease fears of another long and difficult season. Chelsea’s recent dominance in this fixture will hardly encourage them either, with the Blues winning each of the last three head-to-heads. Potter, meanwhile, has never beaten his former club in seven managerial attempts.

Chelsea also enter the contest with plenty to prove. Enzo Maresca’s men looked flat in a goalless draw with Crystal Palace, and in truth they were fortunate to avoid defeat after a late Eberechi Eze free kick was ruled out in controversial fashion. Expectations had been raised following an impressive preseason and success in Europe and domestic cups, but the lack of creativity on Sunday highlighted that some of their summer arrivals are yet to settle. Chelsea will be wary of failing to score in consecutive league games at the start of a season for the first time since 1995-96, while their patchy away record remains a concern.

West Ham are expected to make changes, with Callum Wilson pushing for a first start after featuring from the bench last weekend. Tomas Soucek and Edson Alvarez are also in contention to return to midfield, while Jarrod Bowen once again carries the main attacking burden in the absence of Mohammed Kudus and Crysencio Summerville. Chelsea are still without Levi Colwill, Benoit Badiashile and Tosin Adarabioyo in defence, so Josh Acheampong and Trevoh Chalobah may continue at the back. Nicolas Jackson is available again following suspension, but Joao Pedro is set to lead the line against an opponent he enjoys playing against, having scored six times against West Ham in the past.

Both teams need a response, but neither convinced on the opening weekend. West Ham will be eager to react after their collapse at Sunderland, while Chelsea still look a work in progress despite their talent.

两支仍在寻求新赛季首胜的球队将于周五晚在伦敦体育场相遇，西汉姆联将在英超主场迎战切尔西。这两支球队都经历了令人沮丧的首周末，铁锤帮在桑德兰被击败，切尔西在主场无法击败水晶宫。

西汉姆联的开场几乎不可能更糟了。在光明球场0 - 3的失利暴露了整个球场的弱点，也让球迷质疑格雷厄姆·波特的执教方式。自从上赛季中期上任以来，这位主帅一直未能激发起球队的信心，他已经受到了密切关注，而在如此糟糕的开局后，压力只会越来越大。上个赛季，他们在联赛的最后8场主场比赛中只赢了1场，铁锤帮知道他们必须迅速提高，以缓解对另一个漫长而艰难的赛季的担忧。切尔西最近在这场比赛中的统治地位也很难鼓励他们，蓝军在过去的三场交锋中都取得了胜利。与此同时，波特在七次执教中从未击败过他的老东家。

切尔西也带着很多需要证明的东西进入了比赛。恩佐·马雷斯卡（Enzo Maresca）的球员在与水晶宫（Crystal Palace）的比赛中表现平平，事实上，他们很幸运地避免了失败，因为埃比莱奇·埃泽（Eberechi Eze）最后的任意球被有争议的判罚无效。在季前赛的出色表现以及在欧洲和国内杯赛上的成功之后，人们对球队的期望有所提高，但在周日的比赛中，球队缺乏创造力，这突显出他们的一些夏季新援尚未安顿下来。自1995-96赛季以来，切尔西第一次在赛季初未能连续进球，而他们不稳定的客场战绩仍然令人担忧。

西汉姆联有望做出改变，卡勒姆·威尔逊在上周末替补出场后争取首发。托马斯·苏塞克和埃德森·阿尔瓦雷斯也有可能回到中场，而在穆罕默德·库德斯和克里森西奥·萨默维尔缺席的情况下，贾罗德·鲍恩再次承担了主要的进攻责任。切尔西在后防线上仍然没有科尔威尔、巴迪亚希尔和阿达拉比约，所以阿钱蓬和查洛巴可能会继续担任后腰。尼古拉斯·杰克逊在停赛后再次复出，但若昂·佩德罗将在对阵他喜欢的对手时领衔锋线，他在过去对阵西汉姆联时曾6次进球。

两支球队都需要回应，但在开幕周末都没有被说服。西汉姆联在桑德兰的失利后将急于做出反应，而切尔西尽管有天赋，但看起来仍在努力。
