But the German’s confidence looks to have taken a knock, and Tuchel cranked up the heat on the 21-year-old by demanding more flavour and more substance.
When he hits the spot, there are very few better than the former Bayer Leverkusen forward. But overall, his form has unfortunately been too elusive for the Blues.
It is fair to say his best displays, not just for Chelsea but also for Leverkusen, have often been discovered when he has played as the ‘false nine’.
Tuchel will be hoping Lukaku returns quickly, otherwise he could even start looking longingly at the other Premier League or European tables.
But with Havertz within his reach he has an exceptional ingredient on his plate already. If the accompaniments are correct, he could deputise at the head of the table in Lukaku’s absence.
Tuchel has cooked up some wonderful things for Chelsea this season — and he may have to find another recipe for success if Lukaku is sidelined.
