The 58-year-old Tunisian would later opt not to extend his stay with the side he guided to a back-to-back league double to end the Simba dominance; with Nabi now gone, the pressure is mounting on who will be his successor.
As Young Africans danced and waved through the streets of Dar-es-Salaam during their treble trophy celebrations last week, not many knew it was Nabi Nasreddine's final appearance as the club's head coach.
The 58-year-old Tunisian would later opt not to extend his stay with the side he guided to a back-to-back league double to end the Simba dominance; with Nabi now gone, the pressure is mounting on who will be his successor.
However, through an Instagram post as he paid tribute to Nabi, club vice president Arafat Hajji called for calm amongst the fans saying that the search for Nabi's replacement is already underway.
"We thank him for his achievements for our club; he has given us an extensive reputation of winning three domestic titles in two consecutive years," Arafat noted.
"Coming and leaving is part of football life; Nabi came and has since departed just like the way others came and left in terms of players, coaches and leaders."
He continued: "He (Nabi) is not the first person to leave and will not be the last person who will continue to come to Yanga, and when the time to leave comes, they will go."
"Our fans should keep calm as their management is at work; we request them to trust us and give us enough time because good things are coming," Arafat added.
The banker was also on hand to give an update on the club's top goal scorer Fiston Kalala Mayele who has been linked to several top sides after a successful season.
"Mayele still has a year left on his current contract, but if any club wants to sign him, we are open to discuss with them."
The predator has been in top form, scoring 17 league goals and a further seven on the continent as he guided his side to their first CAF Confederation Cup final.
