Well everyone is excited about Lukaku back in Chelsea but I have doubts over his arrival. He sure had great season in Serie A but he wasn't that good in United. Yeah he scored but his stats in Serie A is far more better than PL. Maybe its the league level or maybe he has now developed? but nothing can't be said for sure.
Can only say things after how he gels up with the current Chelsea squad in 1-2 matches after his arrival.
I think Lukaku will make Chelsea more threatening, having good players assisting him, then this tank will be unstoppable imo. Inter's scudetto was won partially thanks to him (among others) but he did quite good job there. I don't see why he will drop in performance with better squad.
