Manchester City have announced the signing of defender Philippe Sandler from PEC Zwolle.
The Netherlands youth international has joined the Premier League champions for a fee reportedly in the region of £2.5 million.
The 21-year-old, a product of Ajax's famous youth system, is expected to provide cover for Vincent Kompany, John Stones, Nicolas Otamendi and Aymeric Laporte at centre-back, although he can also play in midfield.
Speaking in March ahead of his impending move, Sandler said: "I heard that scouts from Manchester City were watching me, but you do not expect as a player to go from PEC Zwolle to City.
"The best manager in the world, Pep Guardiola, is currently in charge there, and he can teach me a lot, and also the style in which they play football attracts me a lot."
Meanwhile, City have allowed 19-year-old goalkeeper Aro Muric to join Eredivisie side NAC Breda on a season-long loan.
City also announced that 21-year-old midfielder Bersant Celina has joined Swansea City on a permanent deal, worth a reported £3 million.
