Kai Havertz is now a Chelsea player.
A deal bringing the Germany international to Stamford Bridge was finally agreed with Bayer Leverkusen earlier in the week and at £72m he is the club's most expensive signing.
And as explained by club director Marina Granovskaia, the Blues simply couldn't miss the boat on one of European football's most promising youngsters.
"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."
Less than 24 hours after sealing his club-record move to the west London outfit, Havertz reported for the club's Cobham training base for a light session.
With most of the first-team squad away on international duty there was to be no immediate reunion with compatriot Timo Werner, although it won't be long before the pair are training together.
Thanks to the club's official photographer, images of Havertz's first Chelsea training session have surfaced.
The Blues' fitness coaches put the 21-year-old through his paces and there was also some shooting practice for the attacking midfielder.
Upon sealing his long-awaited move to the Premier League, Havertz was clearly thrilled to have made the move from red to blue.
‘I am very happy and proud to be here," he told the club website. "For me, it is a dream come true to play in a big club like Chelsea and I can’t wait to meet all the players and the trainers.
"Yeah, I am very happy to be here!"
