The Mara club officials have made the decision quickly to enable the team to prepare well for this season's NBC Premier League match against Kagera Sugar to be played in Kagera early next week.
Coach Adam has already started work to sharpen his squad in Musoma District, urging the club's fans and businessmen in the region to come together to strengthen their team.
He said the task ahead of him is huge, but it could be easy if all football stakeholders in Mara cooperate with him in the process of rescuing Biashara United which is on the brink of facing relegation this season.
"I have seen that the team is eager to stay in the Premier League next season,'' Adam stated.
The gaffer noted: ''I especially ask for cooperation from every football stakeholder in the region immediately to complete this exercise which is difficult for me, but it may be easier if the cooperation exists."
"I have seen the players in the squad are good, they can fight and get good results in the games we face, this has given me the courage to agree to work for this club because I see something going to happen successfully,'' the tactician noted.
Adam had in the past led Shinyanga's Mwadui FC which has been participating in Mainland Tanzania Premier League for the past two seasons.
Biashara United so far has four games against Kagera Sugar (away), Geita Gold FC (away), KMC FC (home), and Azam FC (away).
The side is positioned 15th in this season's NBC Premier League standings with 24 points from 26 games played.
Biashara United's management has continued to urge football fans and entrepreneurs in Mara to stay with their team in the run-up to the end of this season.
The side needs to win the remaining four games to save itself from the scourge of relegation which continues to haunt the outfit because of recent results.
Biashara United's Secretary-General Mariam Derick noted: ''The leadership continues to fight to rescue the team from relegation, which is why the officials sought to hire coach Adam immediately to replace coach Bahati that left with his assistants earlier this week.''
Mariam said football fans and entrepreneurs in Mara should cooperate with their team that will, at the beginning of next week, confront Kagera Sugar in a Premier League clash.
The official pointed out: ''We continue to encourage the solidarity for each of us in Mara, we believe in unity to overcome this difficult period, each of us is fighting to encourage solidarity, I believe we will succeed."
Marian noted: "Leaders have fought day and night and managed to find coach Adam who has agreed to join us in the battle to keep our club in the Premier League.''
''It is now our collective responsibility to cooperate with him and empower our team to succeed,'' the official disclosed.
