Chelsea can takeover Liverpool transfer scheme with Roberto Firmino heir to keep Tuchel promise

With the gift of hindsight, Thomas Tuchel's decision to replace Romelu Lukaku with Kai Havertz for the Champions League tie with Lille last month feels quite a definitive moment. Four days removed from Lukaku's record-breaking seven-touch display at Crystal Palace, Tuchel made a bold move in an effort to improve a faltering attack.

The effect of that decision has been highly positive. Chelsea have suddenly found a new verve in their play, build-up play has suddenly felt less stale and repetitive, and we have been treated to some great goals.

Part of that is down to Havertz's stunning form, aided by his fellow attacking peers also uncovering good form. Another factor that solidifies the reasoning behind the switch feels symbolic for Tuchel's tenure.

When it comes to distance and sprints is where Carragher's broader point comes into focus. Havertz averages a distance run per 90 of 11km compared to Lukaku's 8.9km and 20 sprints to 10.
