A dilemma for Renault's 2018 driver line up then. At one time Alonso was in the frame. Then Perez, then Sainz, and a few others have also been mentioned. And now Kubica. Who's next??
Apparently Renault has just conducted another secret test for another potential 2018 driver. A spy photo was leaked on the net in the last few minutes....
