Declan Rice came back to haunt former club West Ham as Arsenal moved top of the Premier League, while Manchester United handed Ruben Amorim some relief with a 2-0 win over Sunderland on Saturday. In Mikel Arteta's 300th match in charge, the Gunners proved far too strong for the struggling Hammers in a 2-0 win at the Emirates Stadium to further their ambitions of a first Premier League title for 22 years. Victory came at a cost for Arsenal as captain Martin Odegaard was forced off injured before half-time for the third time this season. Arsenal edge one point ahead of Liverpool, who are in action later at Chelsea. Defeat leaves West Ham still languishing in the relegation zone.
