He is already one of only two managers to have got the better of Pep Guardiola in three successive matches - so how telling will it be if Thomas Tuchel can rack up four wins in a row when Chelsea host Manchester City on Saturday?
The Chelsea boss never beat Guardiola when they both worked in Germany but followed in Jurgen Klopp's footsteps soon after arriving at Stamford Bridge when he racked up a trio of wins in three different competitions in the space of six weeks at the end of last season.
Tuchel's last triumph, in the Champions League final, was by far the most significant of those successes, and came after some so-called over-thinking by his opposite number saw him tinker with the tactics that had just delivered his latest Premier League title.
