Back-to-back defeats to Bordeaux and reigning champions Paris Saint-Germain have seen Marseille fall outside the UEFA Champions League qualification spots, one point adrift of Monaco in fourth position heading into Friday's round 33 fixture at Nantes.
A week after twice surrendering a lead at home to PSG in a 3-2 loss, Marseille went down to Bordeaux via Cedric Yambere's 61st-minute goal on Sunday.
Marseille are now battling it out in the UEFA Europa League places for the first time since week five but Bielsa has not given up hope of leading the nine-time French champions to Europe's premier competition heading into Friday's clash at Stade de la Beaujoire-Louis Fonteneau.
"We are in an uncomfortable situation, but we hope that the position in the standings will be consistent with what the team deserves," Bielsa said.
"We will fight for every point in every game to enjoy every option we have.
"Obviously we do not expect this fall but I think and I hope that we will change all that in the end of the Championship.
"Especially from my point of view, the way to play the team allows to characterise its real possibilities. Losing is always synonymous with pain especially when we could have avoided it and it's part of our job to raise us from those bad times."
