“We just need to keep working, I’ve seen a lot of fire in this team this year,” he told Sky F1.
“I’m very surprised, after such a tough season last year, with how this team was still firing and hungry for results.
“That’s the competitive spirit we need to make sure we continue to have.”
Team boss Andreas Seidl added: “I’m happy for the entire team, everyone has done so much work throughout the year.
“Performing P4 for us is a big step forward, and great motivation for all of us to keep working hard with the clear aim that at some point that we fight for podiums down to our own outright performance.”
