George Russell stopped short of accusing Fernando Alonso of brake-testing him at the Australian Grand Prix.
But he suggested something was strange about the Spaniard's actions late in the race which led to the Briton crashing out. Russell lost control of his Mercedes as he chased down the Aston Martin ahead of him.
He smashed into the wall before careering off into the gravel. His car flipped up onto its side but Russell was able to get out of the car and was unharmed, before he was taken back to the paddock by the medical car.
The incident is under investigation and both drivers have been called to the stewards to explain their perspectives on what happened. Replays appeared to show Alonso slow down before the braking zone which may have been a contributing factor to the crash.
The Spaniard insisted he was looking ahead of him rather than behind at the time. And Russell is happy to give his rival the benefit of the doubt for now, but was clearly suspicious of the Aston Martin driver's actions.
He said: "I've gone off and that's on me, but I was half-a-second behind Fernando 100 metres before the corner and, suddenly, he came towards me extremely quickly and I was right on his gearbox.
"I don't know if he had a problem or not - it's gone to the stewards. That's a bit bizarre in a circumstance like this. I've got nothing more to say right now, I'm just disappointed to end the race like that."

Asked specifically if he felt he had been brake-tested by Alonso, Russell replied: "It's clear that he braked 100 metres before the corner and then went back on the throttle again to take the corner normally - we've already seen the data of that.
"I'm not going to accuse him of anything until we've seen further. But I was right behind him for many laps, was half-a-second behind approaching the corner and then, suddenly, he slowed up very dramatically before going back on the power.
"I wasn't expecting it and it caught me by surprise. That part is on me, but it's interesting that we've been called to the stewards. We'll see what they have to say."
