Chelsea dropped their first points of the season on Sunday as West Ham held Maurizio Sarri's team to a 0-0 draw to leave Liverpool out on their own at the top of the Premier League. Chelsea had won all five of their league matches before the weekend, going toe to toe with Liverpool, who beat Southampton on Saturday to make it six wins out of six.

The visitors had 72 percent possession at the London Stadium but failed to create many clear-cut chances and had to deal with West Ham's constant threat on the break. Sarri bemoaned his side's failure to kill the game off and said West Ham -- who lost their first four matches of the season -- were tough opponents. "In my statistics we had seven opportunities against three," he said.
