Romelu Lukaku got off to a perfect start as he scored on his second Chelsea debut as the club’s record signing inspired a 2-0 win at troubled Arsenal.
Lukaku rejoined Chelsea from Italian champions Inter Milan for £98 million and the Belgian striker made an immediate repayment on that huge investment in the London derby at the Emirates Stadium.
The 28-year-old spent three years at Chelsea between 2011 and 2014, but rarely featured and never scored before being sold to Everton.
Lukaku, who endured a difficult spell at Manchester United before flourishing at Inter, took just 15 minutes to showcase his power and predatory instincts.
Holding off Pablo Mari, Lukaku kept the Chelsea attack going before shrugging aside the Arsenal defender as he surged into the six-yard box to tap in Reece James‘ cross.
Lukaku’s goal was his 114th in the Premier League, making him the competition’s 20th highest scoring player.
James scored Chelsea’s second himself with a superb strike into the far corner after Mason Mount picked out the unmarked defender inside the Arsenal area.
European champions Chelsea have made a flawless start to their title challenge, winning successive games, scoring five goals without conceding.
“I’m very happy with how he has integrated already, a very smart guy who likes to be in the group,” Chelsea manager Thomas Tuchel said.
“He gives us something we did not have, to protect balls. You cannot start better than a goal and he assisted some chances.”
Lacklustre Arsenal were booed off at half-time and Mikel Arteta‘s team are pointless and goalless after following their limp loss at Brentford with a second defeat.
