What's particularly evident about Chelsea right now is the lack of creativity in the final 3rd, which is frankly bizarre given the talent at their disposal. The two behind Lukaku aren't doing enough, they seem incapable of playing useful passes. What I've seen is when they push just inside of the wing with the wing back moving on the overlap, if a centreback of centre mid joins to create an overload, it leaves the wide attacker with too many outside options and only Lukaku in the box. Without Pulisic no one is busting a gut to get in the box. There's just a lack of movement off the ball. Lukaku's ability to make something out of nothing is massive.
