Manchester City went on Tuesday for an eleventh consecutive victory, by strangling West Bromwich Albion on their lawn (0-5).
A real festival of Citizens with goals from Gündogan (6th, 30th), João Cancelo (20th), Mahrez (47th) and Sterling (57th).
With this success, Pep Guardiola's team temporarily seizes the leader's chair in the Premier League, ahead of Manchester United who host Sheffield on Wednesday (9.15 p.m.).
At the same time, Arsenal took revenge on Southampton who had eliminated them three days ago in the FA Cup.
The Gunners won 3-1 among the Saints thanks to goals from Pépé (8th), Saka (39th), and Lacazette (72nd).
With success, Arsenal signs a fifth success in six matches and goes back to 8th place.
