Arsenal provisionally moved top of the Premier League as Declan Rice scored against his old club West Ham United in a 2-0 home victory in a lop-sided London-derby on Saturday.
Midfielder Rice rammed home a rebound in the 38th minute to reward Arsenal's domination against a defensively-minded West Ham who failed to register a shot on target.
Bukayo Saka then made the points safe from the penalty spot in the 67th minute to make it a satisfying 300th game in charge for Arsenal manager Mikel Arteta.
Manchester United cruised to a rare comfortable home Premier League victory as goals from Mason Mount and Benjamin Sesko secured a 2-0 win over Sunderland on Saturday.
With the pressure growing on manager Ruben Amorim after a disappointing start to the season, Mount calmed the nerves around the ground with a fine early finish to break the deadlock.
United continued to dominate, with a spectacular save from Sunderland goalkeeper Robin Roefs preventing Bruno Fernandes from adding a sumptuous second before Sesko netted his first Old Trafford goal after 31 minutes.
Sunderland were awarded a penalty late in the first half, a decision that was overturned following a VAR intervention, but they never really threatened after the break as United eased to a third home league victory of the season.
