Kaltenborn, and team founder Peter Sauber, were not in Monaco on Thursday as the practice action kicked off, with Blick newspaper reporting that they were instead looking for sponsors and partners in eastern Europe.

The Swiss newspaper now reveals that Kaltenborn and Sauber were in the Russian capital.

"We had an important meeting," was all she would tell veteran correspondent Roger Benoit.

Asked, however, if Sauber is now ready to run some new sponsor logos on the C32 car, Kaltenborn insisted: "No!"
