Sebastian Vettel claims Lewis Hamilton "didn't leave any space" when the pair clashed at the Della Roggia chicane on the opening lap of the Italian Grand Prix.
Hamilton dived down the outside of Vettel at the second chicane and took the racing line through the corner, but Vettel found himself pinched and his line compromised. The pair clashed and Vettel span, dropping him to the back of the grid.
Vettel insists the blame was on the Mercedes driver, although the stewards decided to take no action after investigating the incident.

"He didn't leave me any space," Vettel claimed after the race. "I had no other [option] but to run into him and make contact. I tried obviously to get out from there, but I couldn't.
"Unfortunately I was the one that spun around, a bit ironic, but was that way. Then I was looking the wrong way and things weren't looking too peachy."
Hamilton, who won the race, now holds a 30-point lead, but Vettel insists it's not a concern for him and Ferrari.
"From there I think we drove well and tried to recover. We still got a lot of points so it could have been a lot worse.
"It doesn't help when you lose points but it's not the end of the world. We're down at the moment, mostly for the fans, but their support has been incredible.
"Unfortunately we didn't deliver. What can you do. I got spun round and there's not much you can do. I'm not too worried. We have the pace, okay the points gap sounds a lot, but we can get it back."
