Max Verstappen says there was no reason for him to allow Toro Rosso team-mate Carlos Sainz Jr. through during the closing stages of the Singapore Grand Prix.
Verstappen stalled at the start and dropped a lap but was able to recover during the Safety Car periods and wound up in eighth, closely behind Force India's Sergio Perez.
Toro Rosso asked Verstappen to allow Sainz through but the Dutchman refused, with the pair maintaining their positions across the final couple of laps.
"After stalling at the start I thought it was over, as I was pushed to the pit-lane and then re-joined the race one lap behind," said Verstappen.
"But I just kept on pushing and to finish P8 is just fantastic! My pace was great and once again I really enjoyed all the overtaking!
"I don’t think there was any reason for me to give up my position after going from being one lap behind to being back in the points, I think I deserved that P8."
Sainz recovered from an engine glitch to take ninth but says he deserved a chance at attacking Perez.
"I started to overtake and have a lot of fun, climbing back up to P9, behind Max, who was pushing Perez," he explained.
"After seeing him try to overtake him for 10 laps, I just thought maybe I could try during one lap, and if I hadn’t been able to I would’ve given the position back to Max. I just wanted my chance, but he decided not to give it to me. It’s something we need to talk about as a team."
