F1 team Sauber has not paid the February salaries of its Formula 1 staff in full because of cashflow problems according to Autosport magazine.

The Swiss outfit is close to securing a title sponsor and is expected to take the grid at the first event of the season in Australia later this month.

Sauber, Force India and Manor asked F1 boss Bernie Ecclestone for an advance on their championship payments back in November.

Swede Marcus Ericsson and Brazilan Felipe Nasr have been signed to drive for the team in 2016 and both bring millions of dollars in sponsorship with them.
