Chelsea forward Timo Werner is reportedly facing a race against the clock to convince Thomas Tuchel that he is capable of firing the Blues to silverware.
The 24-year-old has scored 10 times and registered 11 assists in 41 appearances for his current side since arriving from RB Leipzig last July.
The Germany international has only managed five Premier League goals, though, and his struggles in front of goal have led to suggestions that Chelsea could be in the market for two new strikers this summer.
As a result, the report claims that Werner is facing a race to impress his manager, with the German's starting role in the team set to be under severe threat next season.
The forward, who was strongly linked with Liverpool before moving to Stamford Bridge, penned a five-year contract with the six-time English champions upon his arrival last summer.
