Chelsea director Marina Granovskaia has revealed her delight at finally securing the signing of Kai Havertz from Bayer Leverkusen, and explained why the Blues moved for the midfielder.
The German international arrives for a club record fee of €80million (£72million), potentially rising to €100million (£90million) with performance-related add-ons.
Havertz, described as a generational talent, has signed a five-year deal at Stamford Bridge and will be one of the squad's highest earners.
Havertz, 21, had asked to leave Leverkusen at the end of last season after Peter Bosz's side failed to qualify for the Champions League.
Personal terms between Chelsea and the attacker had long been agreed but finalising a fee with the Bundesliga club took time.
Chelsea had been the only interested party this summer, with Liverpool, Real Madrid and Bayern Munich taking a step back for financial reasons.
Havertz joins Timo Werner and Hakim Ziyech in the Blues' new-look attack, with Thiago Silva and Ben Chilwell arriving to shore up the backline.
Having finally confirmed such a highly-coveted signing, Granovskaia has admitted how delighted they are to secure such a sought-after starlet.
"Kai is one of the best players of his age in world football, so we are very happy that his future lies at Chelsea," she told Chelsea's club website.
"He has proven pedigree in one of the best leagues in Europe, he plays for the German national side and he is an exciting, dynamic talent.
"We are delighted to be able to add his versatility and quality to the squad before the season begins."
