Don’t think many world class forwards can really score a lot from tuchel system.
They mainly use wingbacks and defenders to orchestrate play and score, most of them are good at setpieces and penalties. For example, I don’t remember many 1v1 chances lukaku had missed or final third passes. I maybe wrong statistically though.
Yes, lukaku is in poor form so is the team’s chance creation.
He’s missed 3 big chances in the PL. Pulisic and Havertz has missed most for Chelsea. 5 each. The top of that table in the PL has Salah, Mané, Kane and Ronaldo. They’ve all missed between 12 and 14 big chances.
I don’t know about WC players. But for players who need space it’s a tough job. Chelsea’s high line is too high when in possession, forcing the opponents to retreat and give less space behind the CBS. So the only obvious vertical passes go diagonally to the wingbacks.
With Lampard Chelsea was playing a high line, but players were encouraged to take more risky passes to the forwards. It result in more chances created for the CF (which Abraham thrives in) but it also resulted in countless turnovers that constantly gave the opponents counterattacking possibilities.
I don’t think any of their regular CBs or CMs really have that killer pass in them. Maybe Thiago Silva and Kovacic, but they don’t use it that much
