It was the 12th match without scoring for the former RB Leipzig frontman, running back to his appearance for Germany in their 6-0 thumping at the hands of Spain in November.
It's worrying signs for the 24-year-old who is noticeably feeling the strain during matches, as told by his frustrated demeanour and lack of confidence when in good positions.
But how do his underlying numbers look?
Werner: 12 games without scoring
Werner has played 786 minutes in that time, making 10 starts and two substitute appearances. He has hit 18 shots on goal, and landed just six of them on target.
In terms of expected goals? Werner's total for those 786 minutes is 3.83xG, meaning we would have expected him to score almost four goals during that period.
But nearly 40% of that total came from a single match, against Leeds United at home. In his last six Premier League appearances, Werner has made just one shot on target and recorded an xG of 1.49.
Werner's creation skills have remained consistent in this period. He has three assists in that period on an xA of 2.42, meaning he is still creating chances for team-mates at a consistent rate.
But this was his first start of those 12 games through the centre. Werner has been shunted out wide, predominantly to the left in Frank Lampard's preferred 4-3-3, and it was his lowest xG of any of those games. He also created zero xA for his team-mates.
Whether it's being accommodated in the wrong positions, or a crisis of form, or a combination of both, Werner has dropped off most noticeably in the most recent of that 12-game run, as the pressure of not scoring is playing on his mind. He most questionably needs a goal - and needs to start getting into positions again.
