The Frenchman tactician was known to be a target for Sundowns' Gauteng rivals Kaizer Chiefs, who are currently searching for a new head coach ahead of the 2018/19 campaign.
The Amakhosi coaching job became vacant following the departure of Steve Komphela, who resigned towards the end of the recent 2017/18 season having failed to win a major trophy with the club.
Carteron has since revealed that Sundowns also approached him about coaching the 2016 Caf Champions League winners, who are currently under the guidance of Pitso Mosimane.
The accomplished South African tactician indicated that he would consider taking a one-year sabbatical after leading Sundowns to the 2017/18 Premier Soccer League (PSL) title last month.
Carteron decided to reject South Africa’s biggest football clubs and join Egyptian Premier League champions Al Ahly.
“I had other offers from Sundowns and Kaizer Chiefs but the priority was definitely for Al Ahly,” Carteron told Egyptian website, KingFut.
The former TP Mazembe coach terminated his contract with United States of America (USA) club side Phoenix Rising FC and he signed a two-year deal with the Egyptian giants.Carteron explained that he joined Red Devils because they are African giants - having won a record eight Caf Champions League titles and record six Caf Super League trophies.
“I am very to sign with Al Ahly which is the African football’s giant. I am still young but I possess great experience I earned through my spells with TP Mazembe and Wadi Degla,” he continued.
“Negotiations were finalised rapidly. I will fight in order to lead Al Ahly to win titles and make the fans happy,” Carteron added.
“I committed to my word with the Red Devils and terminated my deal with Phoenix Rising by mutual consent,” the 47-year-old trainer concluded.
