Barcelona have announced the signing of Andreas Christensen on a free transfer from Chelsea.
The centre-back has moved to Camp Nou after his contract with Chelsea expired at the end of June.
Denmark international Christensen has agreed a four-year deal that includes a €500millon buy-out clause.
Christensen had been linked with Barca for some time after it began to look likely he would not extend his stay in west London.
Barca president Joan Laporta confirmed on Saturday that Christensen's deal would be officially completed and announced this week.
He becomes Barca's second signing of the transfer window, with Franck Kessie's move from Serie A champions Milan – also on a free transfer – having been confirmed earlier on Monday.
Christensen joined Chelsea from Brondby back in 2012 and made his professional debut two years later, but it was only after a two-year loan spell with Borussia Monchengladbach that his Blues career began to take off.
He has made 167 appearances for the club in all competitions, including 26 last season, scoring four goals in total.
A Champions League, Europa League, Club World Cup and UEFA Super Cup winner in his Stamford Bridge career, Chelsea won 92 of the matches in which Christensen featured.
With Christensen and Kessie on board, Barca's focus seems to be on completing a move for Leeds United winger Raphinha.
Chelsea have reportedly agreed a fee with Leeds for the Brazil international, but Laporta insisted Raphinha has indicated he instead wishes to join Barca, who are hopeful of striking a deal despite their financial issues.
Barca are also in talks with Ousmane Dembele over a new deal, with the France winger now a free agent, while Manchester United have an interest in Blaugrana midfielder Frenkie de Jong.
