Robert Kubica, who signed a contract with the Renault F1 Team, is not certain if he will stay with the French team after the announcement of the take-over by Genii Capital, the Luxembourg investment company who is to buy 75% of the outfit.
Daniele Morelli, manager of Kubica, said to 'BBC Sport': "It's a positive reaction but we have asked for more information.
"We would like to know about Genii Capital and who is doing what in the team - a partner can be a sleeping partner or a controlling partner. The cards have changed in respect of when we signed and it's important Renault give us full information.
"We are not against the new position in principle, but it is important to know who will run the team and what kind of strategies they will use. It could be positive or negative.
"We need some time - at least a few days - to evaluate the new situation so I am not in a position to say we will leave or stay."
