I mentioned it earlier in this thread, but Chelsea wasted money on Lukaku imo. Havertz would have been capable of holding down the CF position for the season while they could have financed a Haaland tranfer in the next summer transfer window. Chelsea play a brand of total football. Goals are literally coming from all over the pitch. Havertz in this system is just as effective as Lukaku imo. He runs channels well, holds up the ball, and actually has better interplay. Lukaku is a better finisher, but he's lacking in build up play in this system.
