Brendan Rodgers' first Premier League game in charge of Liverpool has ended in a 3-0 hammering at West Brom.
A stunning volley from Zoltan Gera gave the Midlanders a first-half lead but Liverpool's chances of getting back into the game were written off shortly after the break.
The Reds were reduced to 10 men after Daniel Agger was sent off for a foul Shane Long in the area.
Long's penalty was saved by Pepe Reina but Martin Skertel tripped Long in the box a few minutes later to give the Baggies another attempt from the spot.
Peter Odemwingie powered the ball into the corner to make it 2-0 before substitute Romelu Lukaku added a third with 12 minutes to go. The result is Liverpool's biggest opening day defeat in the top flight since 1937.
Michael Laudrup enjoyed a dream debut as Swansea manager. His side won 5-0 at QPR, with two goals each for Michu and Nathan Dyer.
Fulham also had an opening day to remember by putting five past Norwich. New signing Mladen Petric bagged himself a brace at Craven Cottage in a 5-0 win.
Arsenal began life without Robin van Persie with a 0-0 draw at home to Sunderland. Olivier Giroud, Santi Cazorla and Lukas Podolski all made their debuts but they couldn't break down the Sunderland defence.
Newly promoted Reading drew 1-1 with Stoke thanks to a last minute penalty from Adam Le Fondre. Michael Kightley had put Stoke in front after 34 minutes.
Kevin Nolan scored the only goal of the game as West Ham marked their Premier League return with a win at home to Aston Villa.
