Jose Mourinho's future as Chelsea manager looked increasingly uncertain after Liverpool beat them 3-1 in the Premier League with Philippe Coutinho scoring twice at Stamford Bridge.

Champions Chelsea's third home league defeat of the season left them in 15th place in the table with 11 points from 11 games - the worst ever start to a season by the reigning champions.

Top scorers
11 Jamie Vardy (Leicester City)          
7  Riyad Mahrez (Leicester City)         
    Odion Ighalo (Watford)                 
6  Olivier Giroud (Arsenal)               
    Alexis Sanchez (Arsenal)               
    Sergio Aguero (Man City)        
    Georginio Wijnaldum (Newcastle)

Elsewhere, Manchester City needed a late Yaya Toure penalty to beat Norwich City 2-1 and retain top spot on goal difference from Arsenal who routed Swansea City 3-0 away.

Leicester City are up to third thanks to a 3-2 victory at West Bromwich Albion where they trailed, with Jamie Vardy scoring for the eighth Premier League match in a row.

Manchester United dropped to fourth after a 0-0 stalemate at Crystal Palace.

Chelsea's hopes of retaining the title look forlorn with six league defeats already and Liverpool's fans, celebrating a first league win for new manager Juergen Klopp, taunted Mourinho with chants of "You're getting sacked in the morning".

While Chelsea lurch from crisis to crisis - they have lost nine times in all competitions including their midweek defeat on penalties by Stoke City in the League Cup which they won last season - Liverpool are buoyant.

They are on 17 points and have moved up to seventh.

Fifth-placed West Ham United lost 2-0 at Watford, their first away loss of the season, while Newcastle United stayed in the bottom three after a 0-0 draw at home to Stoke City.
