The legendary Red Devils manager has been at the helm of the club for 26 years, winning 13 Premier League trophies as well as many more national cup competitions and European trophies in the process.
They may be bitter rivals but Manchester City captain Vincent Kompany still praised ‘Fergie’s’ Scots influence.
“Sir Alex, one of the best managers of all time. After 26 years of success in the game, we all owe him a tribute,” said Kompany.
Arsenal legend Patrick Viera, who is currently Manchester City’s Football Development Executive, also praised the Manchester United coach.
“It is the end of an era for a truly great ambassador, not only for the Premier League but for football overall. Best of luck Sir Alex,” tweeted the man who was born in Senegal.
Ghanaian duo Kevin-Prince Boateng and Michael Essien also took to the social networking platform to praise the former Aberdeen manager.
“A legend and one of the greatest managers ever. Good luck in your retirement. #respect.” tweeted Essien, while Boateng simply said: “End of an era… #siralexferguson #manunited.”
Former Bafana Bafana and Charlton Athletic defender Mark Fish also had great things to say about the footballing icon.
“If all the rumours are true. Good bye True Great!! Well done to Sir Alex Ferguson on being just Awesome!!” tweeted Fish.
