- Chelsea manager Andre Villas-Boas under further pressure after 1-0 defeat at West Brom
- Robin van Persie brace hands Arsenal 2-1 win over Liverpool at Anfield
- League leaders Manchester City move five points clear with 2-0 win over Bolton
Andre Villas-Boas' troubles as Chelsea manager deepened on Saturday as he watched his side go down to a 1-0 defeat at West Bromwich Albion in the English Premier League.
An 82nd minute strike by defender Gareth McAuley was enough to sent the Blues' crashing to a seventh league defeat.
The result also means they lose ground on London rivals Arsenal in the race to finish fourth place and secure Champions League football next season.
"It wasn't good enough and it's not been good enough for quite some time. We don't win enough games and they are not numbers that make us proud. In football there is joy and there is pain," Villas-Boas told BBC Sport after the game.
Robin van Persie's deft injury-time volley gave Arsenal all three points against Liverpool at Anfield.
Liverpool were awarded a penalty in the 19th minute when Tomasz Szczesny brought down Luis Suarez, but made amends palming Dirk Kuyt's spot kick to safety.
But four minutes later the Reds went ahead when Laurent Koscielny turned the ball into his own net as he tried to divert Jordan Henderson's cross.
But the lead didn't last long as van Persie headed home his first from a Bacary Sagna cross in the 31st minute.
The game looked to be heading for a draw when the Dutch striker caressed the ball past Pepe Reina in the second minute of injury time to leave Liverpool 10 points adrift of a Champions League place.
Arsenal are now three points clear of Chelsea in fourth place with 49 points.
League leaders Manchester City enjoyed a comfortable 2-0 win against Bolton Wanderers at the Etihad Stadium.
A 23rd-minute own goal by Icelandic defender Gretar Steinsson handed Roberto Mancini's team the lead. Mario Balotelli's 14th goal of the season in the 69th minute ensured all three points and a five-point lead at the top of the table.
