The French tactician is understood to be in advanced talks to take over at Jangwani Street-based outfits after the team had offloaded coach Cedric Kaze.
Migne, former Kenya's national side 'Harambee Stars' head coach, is expected to take charge of Yanga when the season will resume after a 21-day break.
Yanga, before the season went into a break to honour former President, the late John Pombe Magufuli, were leading the top flight with 50 points.
However, Mogella, who also played for Yanga, stated that the Frenchman should not be put under intense pressure especially this season.
"He needs magic or a miracle in order to ensure he does a great job because the remaining time of the season is not enough for him to have a complete overhaul of the club," the retired forward said.
He stated: "He would need time and so he should not be judged for what he will do within a short period and seen as one who cannot handle the club.''
Mogella insisted: "Migne is the right coach but Yanga fans should not put him under so much pressure to deliver so much this season."
With technological advancement it is easy to say Migne has been busy analysing Yanga players through Premier League matches' videos provided, as well as those on the club's youtube channel.
The new head coach is expected to land in Dar es Salaam this week and he will be assisted by coaches from five different countries.
Initially, Migne reportedly wanted to influence a choice for assistant coach position but the club insisted Juma Mwambusi will be maintained.
Razak Siwa is Yanga's new goalkeepers' coach, who has been working with the club for the last two days.
The former Kenya's Bandari keepers' tactician has been asked to ensure Yanga keepers will be different and very fit in the next three months.
Physiotherapist Ghanaian Edem Mortotsi will be working under Siwa after he was retained when the club made technical changes that saw Kaze leave the team.
The Ghanaian expert was brought to the club by Kaze but Yanga were satisfied he was not to blame for the poor results, which is why he was not shown the door when the reshuffle was done.
Nahumu Muganda has been appointed from Ihefu FC as Yanga's another doctor and he is coming to replace Sheky Mngazija, who asked to leave his post.
Hafidh Saleh will remain as the team manager while Mohamed Omar will work as the kit manager.
Should Migne arrive to take charge of the Dar es Salaam club, he would be the third coach to oversee them this season.
In the beginning, Zlatko Krmpotic was appointed but the former Zesco United tactician lasted for only 37 days.
Kaze was later appointed but a string of draws and a 2-1 loss to Coastal Union at the beginning of March sealed his fate as the head coach.
