The pair made contact at turn 11 when Ocon, sporting newer tyres, attempted to make a move on his team mate, only to have to go off track.
"I was on a different strategy, I had more pace at the end," Ocon said. "I went to the outside but he didn’t leave any space so we collided and I had to go off track."
"It happens. We fight together, we touched a little bit, there’s not a drama about it. Probably it didn’t break much, the car felt OK at the end. I pulled out two seconds on the last lap so that was still good," he added.
Wehrlein meanwhile questioned Ocon's version of events.
"If he would watch to the right side I think there was more than 100 metres left for him, so if it’s not enough, I don’t know," he said. "I think the guy on the inside maybe didn’t have enough room but if it was him on the outside and he didn’t have enough room I don’t know. I don’t know what he said."
"Nothing happened so in the end we both went wide and cut the chicane. There was a big pace difference at this time from the tyres."
