Vincent Kompany has announced that he will leave Manchester City this summer – drawing the curtain on an 11-year spell with the domestic treble winners – and that he will make a shock return to the Belgian club Anderlecht as player-manager.

In an two-part open letter on his Facebook page that was released the morning after he led City to a resounding FA Cup final victory over Watford, the City captain revealed the game had been his last for the club before explaining that he will take over at Anderlecht, where he began his career.

Kompany wrote: “Not so long ago, I took a call from RSC Anderlecht. Quite unexpectedly, they offered me the position of player-manager. Michael [Verschueren, the sporting director] and Frank [Arnesen, the technical director] explained to me in detail how they saw it working in practice. They had thought it through. I was left not only impressed, but also intrigued by this sign of confidence in me.”

“Pep Guardiola reignited my love for the game. I’ve witnessed, participated, analyzed, absorbed, studied. Man City play the football I want to play. It is the football I want to teach and to see played. I have decided to take up the challenge at RSC Anderlecht. Player-Manager.

“This may come as a surprise to you. It’s the most passionate yet rational decision I’ve ever made. As a footballer, I was born and raised at RSC Anderlecht. Since the age of six, I have been one with that club. A history of 34 league titles, they are second to none.”
