Bayern Munich announced the signing of Juventus defender Matthijs de Ligt on a five-year deal on Tuesday with the Dutch international expected to become "a mainstay" as the German champions embark on the post Robert Lewandowski era.
"Matthijs de Ligt was a top target for us. With signings like this, the big aims that we have are achievable. The future face of our team is increasingly taking shape," said Bayern president Herbert Heiner.
Reports in the German media put the cost to Bayern of securing the Dutch central defender at 70 million euros plus 10 million in bonuses ($82 million in total).
Bayern will use the proceeds from the transfer of Polish striker Lewandowski to Barcelona, estimated at more than 45 million euros, to help finance the move.
"This transfer is an important building block in the overall concept that we're gradually putting into place. De Ligt should become a mainstay at FC Bayern" added Hainer.
His arrival follows that of Sadio Mane from Liverpool as Bayern.
De Ligt joined the Ajax academy at nine years of age, making his debut for the record Dutch champions at 17.
He became their youngest ever captain and in 2019, after 117 appearances (13 goals) and the league and cup double, he moved to Juventus.
Alongside the likes of Frenkie de Jong, Donny van de Beek and Hakim Ziyech, De Ligt lifted Ajax to within seconds of the 2019 Champions League final.
A goal in the sixth minute of injury time in that 2019 semi-final saw Tottenham dash that dream.
His time with Juve earned him more silverware, with a Serie A title, an Italian cup and Super Cup.
On the international stage he was the Netherlands' youngest debutant since 1945, and has gone on to earn 38 caps for his national side, scoring twice.
He said he had been won over by Bayern's sales pitch.
"I felt the genuine appreciation from the sporting management, the coach and the board right from the start, which convinced me," he told a press statement issued by the buying club.
"On top of that, FC Bayern is a brilliantly run club with big aims. I'm very glad that I'm now becoming part of the FC Bayern story."
Bayern chief executive Oliver Kahn suggested that as good a player as De Ligt is, his character could also prove to be enormously beneficial to Bayern.
"Matthijs de Ligt has impressed at the highest international level, not just with his technical qualities but also as a character who leads in all his teams," said Kahn.
He added: "At his young age he's already learned about taking responsibility. A strong team doesn't just require a strong attack, and with this signing we're really raising our defence to the top level."
