The Mwanza squad is currently one of the domestic top flight clubs that are struggling to escape relegation to the First Division (FDL).
Minziro's first task was Mbao FC's yesterday's league encounter with Tanga's Coastal Union which was set to take place in Mwanza.
After the yesterday duel, Mbao FC will be left with seven games, which could determine the squad's future at the top level of domestic soccer.
Minziro, who had recently coached Mwanza's other Premier League squad, Alliance FC, stated he had five days to improve his players' fitness.
''I have opted for few changes and now my players are to a certain extent fit given I put them through their paces to improve stamina and endurance,'' he stated.
''With the players having returned from a break brought about by the COVID-19 pandemic, most of them had probably not trained well during the break given they are not fit.''
''I have, for that matter, improved their fitness given a soccer player can not excel in the game should he be found wanting in the aspects.''
He noted he has a challenging task of helping the outfit regroup and perform well, given they are not in safe position in the league standing.
He added that they for that matter need to win all of their matches and ultimately be certain of a spot they will be in.
"We need to win every game. Every game has to be perceived as a final then we will be cetain of a spot we willl be in,'' he disclosed.
Before the yesterday duel Mbao FC had been positioned 19th in the 20-team Premier League table.
They had registered 23 points in 30 matches, with eight matches left to conclude the season
