The Dutchman and title rival Hamilton were battling for position on track at Monza following the first round of pitstops as they ran wheel-to-wheel after the pitlane exit.
Hamilton defended the inside into the first chicane, with Verstappen attempting to go around the outside and claim the apex for the left handed exit.
However, he ended up bouncing over the kerbs and was launched over Hamilton’s car – putting them both out on the spot.
Verstappen insisted that there was plenty of room for the pair of them to run side-by-side, but says the clash became inevitable once he was pushed on to the sausage kerb.
“We realized it was going to be close into Turn 1,” he told Sky. “[Hamilton had to] cut across after the white line [at the pitlane exit] and I had to go on to the green part to not touch.
“I went around the outside. And of course, he realized I was going for it. So he just kept on squeezing me.”
He added: “I didn’t expect him to just keep on squeezing, squeezing, squeezing, because he didn’t even need to.
“Even if he would have left me just a car’s width, we would have raced out of Turn 2 anyway. And I think he would have probably still been in front.
“But then he just kept on pushing me wider and wider. And at one point, there was nowhere to go.
“He just pushed me onto the sausage kerb. And that’s why, at the end of the day, we touched because of the rear tyre.”

Verstappen felt that there was no similarity between what happened at Monza and their crash the pair had at the British Grand Prix
“I wanted to work with him because I wanted to race,” he added. “Of course people then automatically start talking about Silverstone, but these things happen.
“Of course, it was not nice at the time. But I think we’re all professional enough to just get on with it and keep on racing each other.”
Verstappen said that if the pair wanted to race fairly then they needed to work together, something he felt wasn’t happening right now.
“You need two people to work together, right?” he explained. “So if you one guy is not willing to work, then what do you do? It’s still going to happen.”
Asked if he planned to talk to Hamilton in private about the situation, Verstappen said: “I think we’re professional enough to step over it and just keep on going.”
