Sauber's financial woes continue to rumble on with fresh reports claiming the team has yet again failed to pay staff in full.
Prior to the start of this year's championship Sauber admitted that they had were late to pay their staff, a situation that was quickly rectified.
Sauber team boss Monisha Kaltenborn cited the "cost-intensive" first few months of a F1 season, saying several factors including from sponsorship transfers as the cause.
She added that it would be "precise one delay."
However it appears the team's troubles have not been resolved.
According to the Neue Zurcher Zeitung newspaper, Sauber are once again in arrears with March's salaries.
Team spokesman Robert Hopoltseder confirmed: "The worries of the last few weeks are not off the table. We currently live from hand to mouth."
Sauber have yet to score a single point this season with Marcus Ericsson achieving a best result of P12 at the Bahrain Grand Prix.
