Vincent Kompany announced on Sunday that he will leave Manchester City after 11 trophy-laden years to become player-manager of Anderlecht.
Belgian defender Kompany joined City in 2008 and made 360 appearances, winning four Premier League titles, two FA Cups, four League Cups and two Community Shields.
The 33-year-old signed off with victory in the FA Cup final on Saturday, where the club captain lifted the trophy after City thrashed Watford 6-0 to complete a domestic treble.
"As overwhelming as it is, the time has come for me to go. And what a season to bow out," Kompany said.
"I feel nothing but gratefulness. I am grateful to all those who supported me on a special journey, at a very special club."
Anderlecht is the Belgian club where Kompany began his professional career before joining Hamburg and he admitted he is relishing the chance to move into management.
"I choose to be grateful for the past but remain ambitious and driven for the future. For the next three years, I will take up the role of player-manager of Anderlecht. Belgium's finest," he wrote on Facebook.
"This may come as a surprise to you. It's the most passionate yet rational decision I've ever made."
Kompany has been ravaged by injuries in recent years and he featured in only 17 of City's 38 league games this season because of muscle problems.
He also paid tribute to his team-mates and manager Pep Guardiola.
"It's cliche to say it but it's also so true: without my team-mates, I would have never been here today," he said.
"We fought many battles together. Side by side. In good times and in bad. So to all of you, from the 2008-2009 squad to today's domestic treble winners: I owe you guys!
"A special word also to Pep and the backroom staff: you've been superb. You've followed me through so much hardship. You made me come back stronger every time. Thank you so much."
In September, City will hold Kompany's testimonial match, from which he will donate all profits to Manchester's homeless.
