OM parted company with former coach Elie Baup last Saturday following defeat on Friday night against Nantes, their ninth loss in 13 competitive games.
Anigo has been installed until the winter break and presided over Marseille's conclusion to a miserable Champions League campaign when defeat to Borussia Dortmund - their sixth in succession - left them without a point.
Now Anigo will look to stop the rot in the league which have seen them go down to two successive defeats when they travel to Lyon, and Fanni has explained Anigo's approach.
He told a press conference: "It's going very well. He tries to unite the group a little more.
"He wants to bring out the rage in us using the frustration...defeats. He wants us to have the hatred of defeat.
"He is a little harder than Elie Baup, but he is not a torturer.
"He just wants to make the most of the group and strengthen unity. He sometimes uses strong words. Okay."
Marseille will confront a Lyon side who finished top of their Europa League group with victory at Guimaraes on Thursday.
Remi Garde's side are enduring a mediocre domestic season and are firmly in mid-table although they have taken four points from their last two games.
Garde told a press conference: "This (Marseille) is a team with a lot of talent that has seen difficult times.
"Vis-a-vis we are very suspicious of their ability.
"We must be on top on Sunday. It remains a big game. We must be at our best individually and collectively."
