LONDON - Diego Costa scored for the second match in succession as Chelsea made it two Premier League wins from two matches this season with a 2-0 victory at home to newly-promoted Leicester City on Saturday and now leads the points table.
After a goalless first half, Chelsea twice almost took the lead at the start of the second period.
Oscar hit the far post with a curling shot from the right before Branislav Ivanovic's header was well saved by Kasper Schmeichel, son of former Manchester United goalkeeper Peter.
Leicester, who held Everton to a 2-2 draw last week, then had a chance of their own when David Nugent burst clear only for the Foxes striker to be denied by Thibault Courtois, again preferred by Jose Mourinho to Petr Cech, when one-on-one with the keeper.
But Spain striker Costa, who scored in last week's 3-1 win at Burnley, marked his home debut by turning in Ivanovic's cross from eight yards out in the 63rd minute.
Chelsea then doubled their lead at Stamford Bridge when Eden Hazard's 77th-minute shot beat Schmeichel after deflecting off Leicester defender Wes Morgan.
"I don't forget they had a good chance with the result 0-0 but we had so many chances, so many opportunities to score obviously we deserved the victory," Chelsea manager Mourinho told Sky Sports.
Arsenal whose bid for the title in recent seasons has so often been undone by poor away form, came from 2-0 down to draw 2-2 at Everton.
The Gunners scored twice inside the final seven minutes at Goodison Park, with France striker Olivier Giroud's 90th-minute goal ensuring a share of the points for Arsene Wenger's side.
Everton went ahead in the 19th minute when unmarked defender Seamus Coleman headed in Gareth Barry's cross at the far post before Steven Naismith, seemingly offside, made it 2-0 on the stroke of half-time after Romelu Lukaku had outmuscled Germany World Cup-winner Per Mertesacker in the build-up.
But then came Arsenal's late recovery.
Aaron Ramsey turned in Santi Cazorla's low centre before half-time substitute Giroud headed in Nacho Monreal's cross.
Swansea, fresh from their shock opening day victory away to Manchester United, made it two wins from two with a 1-0 success at home to Burnley secured by winger Nathan Dyer's 23rd-minute goal.
