Manchester City have confirmed the signing of Chelsea star Mateo Kovacic on a four-year deal reportedly worth £25million.
The Croatia star's new contract will keep him at the Etihad until the summer of 2027, and is the club's first signing of the window.
The English champions first opened discussions with their Premier League rivals at the beginning of June, ahead of Kovacic's international duty.
The 29-year-old midfielder is widely tipped to replace outgoing midfielder Ilkay Gundogan, who has joined Barcelona as a free agent after a final record-breaking season as club captain.
Kovacic joined Chelsea on loan from Real Madrid during the 2018-19 season, and bought permanently by the west London outfit as their only sanctioned purchase during their two-transfer-window ban.
The player, long a lynchpin of the starting XI, has helped the Blues win the Europa League and the Champions League - the player's fourth - during his 221 appearances for the club.
Upon signing, Kovacic was effusive in his praise for the club and their manager, Pep Guardiola.
'This is a brilliant move for me, and I cannot wait to get started with City,' he said.
'Anyone who has watched this team under Pep knows how good they are – for me, they are the best in the world. The trophies they have won are clear for all to see, but they are also the best footballing side out there.
'To be joining this squad really is a dream for any footballer. I still have plenty of learning and developing to do, and I know under Pep's management I can become a better player, which is really exciting for me.
'My plan now is to rest for a few weeks before coming back to Manchester to prepare for the new season. I want to help this club stay at the top and win more trophies.'
