Valtteri Bottas says his second clash in three races with Kimi Raikkonen was just "unlucky" as the duo came together in the Mexican Grand Prix.
Raikkonen took Bottas out of the Russian Grand Prix on the final lap, and at Autodromo Hermanos Rodriguez the situation was reversed.
The Ferrari driver had to retire from the race after Bottas' left-front tyre made contact with Raikkonen' rear-right as they fought for position.
Unlike in Russia, the stewards deemed no further action was needed and Bottas went on to finish on the podium.
The Williams driver downplayed the incident.
"I don't know. We shouldn't really speak about it," said Bottas. "We were racing hard obviously but we are normally used to it.
"It is unfortunate when you go into a chicane like that. I was fighting for the position. There was a decent possibility to get through but it ended up like this. It was just unlucky."
"We had contact in Russia but it was just unlucky we got together again. I was close to Turn4/5 and I was inside Turn 5 and we collided. It was a shame."
Bottas admitted he was delighted to return to the podium.
"Overall a really good race, very happy," he said. "The team did a great job today especially with strategy. The guys were on it, so I'm really pleased with that."
