MANCHESTER, ENGLAND (REUTERS) - Premier League leaders Chelsea hammered bottom club Norwich City 7-0 at Stamford Bridge on Saturday (Oct 23) and Manchester City cruised to a 4-1 win at Brighton & Hove Albion, while Everton collapsed to a shock 5-2 defeat at home to Watford.

England international Mason Mount struck a hat-trick for Chelsea who showed no lack of firepower despite the absence of injured forwards Romelu Lukaku and Timo Werner.

Mount opened the scoring in the eighth minute before winger Callum Hudson-Odoi scored 11 minutes later when he collected a fine pass from Mateo Kovacic and provided a cool finish.

Manchester City remain two points behind Tuchel's side after another impressive display on the south coast.

Phil Foden scored twice for Pep Guardiola's side as they opened up a 3-0 lead within the opening 31 minutes.

The visitors were on the front foot from the outset at Brighton and took a 13th minute lead through Ilkay Gundogan after a mistake from home goalkeeper Robert Sanchez.

City soon extended their lead as Foden got his first of the match, steering Jack Grealish's sq...
