LEAKY AT THE BACK
Bernd Leno - 6
Could not have done anything about the two goals as his defence were exposed time and time again. Made a superb save late on from a Lukaku header.
Cedric Soares - 6
Offered more protection in defensive situations than Kieran Tierney did on the other side.
Failed to receive much help from Nicolas Pepe when it came to tracking back. Did his best to curtail Marcos Alonso and Kai Havertz even if he was not always successful.
Rob Holding - 5
Both he and Pablo Mari were taught a lesson by Lukaku when it comes to the physicality of the Premier League.
It was a baptism of fire for Rob Holding given it's his first game of the season.
But he was still sluggish, even if Mari did him no favours. He was frequently susceptible to being beaten in the air in the same way Ben White struggled against Brentford. Received a yellow card for his troubles.
Pablo Mari - 3
Clearly not capable of handling someone of the calibre of Lukaku. Allowed the Chelsea striker to wander through and tap in from close range inside the first quarter of an hour.
Alongside a second central defensive partner in as many games following the omission of White, Mari failed to show any kind of chemistry with Holding. To cap things off, he was also booked. Had an absolute nightmare.
Kieran Tierney - 5
Looked lively early on as Arsenal clearly targeted the right-hand side of Chelsea's defence.
But was caught out for Chelsea's opener as he got drawn inside and allowed Reece James acres of space to pick out Lukaku.
The visitors enjoyed tremendous joy down the left as the second goal also came from a similar position.
