Chelsea splashed €80 million in the summer of 2020 to bring Kai Havertz to Stamford Bridge. However, the Bayer Leverkusen prodigy has had an indifferent stint at the Premier League giants thus far.
The 22-year-old has made 70 appearances for the Blues across competitions, bagging 14 goals and 12 assists. Five of those goals and two of the assists have come this season. Havertz remarkably scored the winner in the Champions League final against Manchester City last season as the Blues won the competition for the second time.
Predominantly an attacking midfielder, Havertz has also found success when deployed further up the field. Tuchel will look to his countryman to deliver the goods as he looks to end his first full season at Stamford Bridge on a high.
#2 Mason Mount - €75 million

Mason Mount is one of the best players to have emerged out of Chelsea's academy in recent years.
The 23-year-old has grown in leaps and bounds since his Blues debut almost three years ago. Mount has made close to 150 appearances across competitions for the club, tallying nearly 50 goal contributions (24 goals, 22 assists).
The England international has been especially consistent in the Premier League, bagging at least six goals in each of his three campaigns in the competition.
Mount has caught the attention of several top teams across Europe, but remains a key player at Stamford Bridge for now.
#1 Romelu Lukaku - €100 million

Romelu Lukaku returned to the Blues last summer after playing a stellar role in Inter Milan's first Serie A triumph in 11 years.
However, the Belgian has failed to live up to his €113 million price tag. After a bright start, Lukaku has blown hot and cold, scoring eight times in 24 games across competitions.
A controversial interview where he criticized manager Thomas Tuchel's tactics has only exacerbated his situation at Stamford Bridge.
Nevertheless, Tuchel will hope that his star man can rediscover his early-season form as Chelsea seek to end their campaign on a high.
