Agree, I'm personally still not 100% sure on Lukaku because he only has a strong body and good finishing but doesn't have the speed, about his movement that is not so fast it can still be covered by his strength. Still waiting for Chelsea and Lukaku against better teams like City, if Lukaku is still unstoppable then I admit I was wrong about him. But anyway, congratulations to Chelsea and as always, there's a lot of work and effort that Arsenal have to do if they don't want to be relegated at the end of the season.
Next up is Liverpool against them and that would be very good test for both teams. Both teams have strong players and it would be also a good test for Lukaku to go up against Van Dijk and Matip who so far have played really well in starting two matches. It would be a thrilling contest to watch.
