Premier League roundup: Hazard and Pedro keep Chelsea perfect under Sarri
Chelsea stretched their perfect Premier League start to four games after second-half goals from substitute Pedro and Eden Hazard gave them a 2-0 home win over Bournemouth.
The result left Chelsea joint top with Liverpool on a maximum 12 points, with either Watford or Tottenham Hotspur able to move level with the early pace-setters when they meet at Vicarage Road today.
The home team dominated a dour first half at Stamford Bridge but it was Bournemouth who missed the best chances through Callum Wilson and former Chelsea defender Nathan Ake before Pedro broke the deadlock in the 72nd minute.
The Spaniard beat visiting keeper Asmir Begovic with a low shot from the edge of the penalty area after a fine one-two with Olivier Giroud and Hazard sealed the contest in the closing stages with an arrowed shot from eight yards.
“I’m really very happy with my players," Chelsea manager Maurizio Sarri told BBC's Match Of The Day. "For us now it’s not important to think of Matchday 4, it’s important to think of the next match.
“At the moment we are doing very well but we can improve."

Substitute Adama Traore struck the winner in stoppage time for Wolverhampton Wanderers as they beat bottom team West Ham United 1-0 at the London Stadium to pile the pressure on Manuel Pellegrini's side.
After a turgid first half, both teams burst into life in the second period and West Ham's Lukasz Fabianski and Wolves goalkeeper Rui Patricio had to pull off a string of fine saves between them to keep the game scoreless, including one stop Patricio made with his face to deny Marko Arnautovic.
the game looked like finishing scoreless until Ruben Neves won the ball back high up the pitch in stoppage time.
The ball was worked on to Traore, who gleefully smashed it into the bottom corner to give Wolves their first Premier League win of the campaign, while West Ham, whose fans booed and whistled loudly at the final whistle, have now lost four in a row.
"It feels good, even if we didn’t win the boys worked hard," winning manager Nuno Espirito Santo told BBC's Match Of The Day. "Both teams could have won but in that moment were more in control. We were in control in the first half. Happy for the fans, it is massive to come a long way and get three points."
Glenn Murray scored twice as Brighton & Hove Albion came back from two goals down to draw 2-2 with Fulham at the Amex Stadium in the first ever top-tier meeting between the sides.
Murray gave Brighton hope on 67 minutes when he side-footed home moments after Aleksandar Mitrovic looked to have set up a Fulham win with his fourth goal in three games.
But the Serb's joy was short-lived as he then handled in his own area to concede a penalty, which Murray took after Pascal Gross had missed from the spot in the first half.
Fulham's Andre Schurrle opened the scoring on 43 minutes for his second goal in successive games.
Everton gave a Premier League debut to new signing Lucas Digne who marked the occasion with an assist but the hosts were frustrated by a dogged Huddersfield Town as they were held to a 1-1 draw at Goodison Park.
Huddersfield took a surprise 34th-minute lead when Phil Billing headed past goalkeeper Jordan Pickford from a corner.
But the lead was wiped out almost immediately when left back Digne's cross was guided home by Dominic Calvert-Lewin.
Southampton earned their first win of the season with an impressive 2-0 victory at Crystal Palace.
Danny Ings, on loan from Liverpool, scored his second goal of the season in the 47th minute to put Southampton ahead and they should have doubled their lead but Charlie Austin saw a penalty saved by Palace keeper Wayne Hennessey.
With Roy Hodgson's side piling forward in search of an equaliser, Southampton struck on the break with Pierre-Emile Hojbjerg's finish making sure of the victory in stoppage time.
