Audi driver Andre Lotterer drove for Caterham in Belgium, replacing Kamui Kobayashi. Will the German be back behind the wheel of the CT05-Renault soon?
After Andre Lotterer's surprise Belgian GP debut, it seems likely that neither the reigning Le Mans winner nor Kamui Kobayashi will be in the Caterham next weekend at Monza.
"As a driver," Japanese Kobayashi told Speed Week, "I do not understand or accept the decision. But I do have some understanding of the situation of the team."
Caterham said Kobayashi remains part of the team for now, but Kobayashi commented: "We are talking, but there is still nothing certain yet.
"The decisions are not in my hands."
Specialist Spanish reports claim the two leading candidates to drive Kobayashi's car at Monza are the Red Bull-backed Carlos Sainz Jr, and fellow Spaniard Roberto Merhi.
