STAMFORD BRIDGE, LONDON—Jose Mourinho's Chelsea were left frustrated on Wednesday after a goalless draw with West Ham United saw them lose ground in the Premier League title race.
Manchester City now top the table after thrashing Tottenham Hotspur 5-1, while a day earlier Arsenal had dropped points when drawing 2-2 with Southampton.
The Blues had an incredible 39 shots on goal against the Hammers—who managed just one—but still they couldn't find a way through as Sam Allardyce's men held firm for a valuable point.
It left Mourinho cutting a frustrated figure, and while he described West Ham's tactics as being somewhat dated, plenty of other talking points reared their head at Stamford Bridge.
