Chinese GP runner-up Kimi Raikkonen has blamed Sergio Perez for their coming together, saying it cost him understeer.
After being bogged down at the start of the 56-lap grand prix, Raikkonen fought his way back up to the front.
However, with tyre strategy, pit stops and DRS all playing a role in Sunday's race, the Lotus driver was forced to cut his way through the traffic on several occasions.
And one of those put him in direct contact with McLaren's Perez.
Trying to pass the Mexican driver, Raikkonen reckons Perez pushed him wide, resulting in the two touching and a broken nose for Raikkonen.
Despite the damage, he continued, working his way up to front where he finished second behind Fernando Alonso.
"I think in the end it was an OK result," Raikkonen said. "Obviously we want to win.
"After a bad start, the car was handling well.
"Overtaking Perez, I was next to him and he just pushed me on the kerb. I tried to avoid him and when on the grass and I hit him.
"It damaged the nose but luckily it didn't damage too much the handling, just a bit of understeer.
"Anyhow, good points and we try to do better next time."
