Daniel Ricciardo says he expects an apology from Red Bull team-mate Daniil Kvyat for triggering a first lap collision at the Russian Grand Prix.
Kvyat braked late into Turn 2 and struck the back of Sebastian Vettel, which sent the Ferrari driver into the path of Ricciardo, causing damage to the Australian's RB12.
Ricciardo was forced to pit for repairs following the incident and trailed home in 11th place, after completing the remainder of the race on a single set of Medium tyres.
"I expect an apology, put it that way," Ricciardo said when asked of Kvyat's approach on the first lap.
"I think he owes it to a few people, so let's see.
"We thought we’d try the Medium tyres but that wasn’t really working.
"Unfortunately the damage was so much that we didn’t really learn anything from the race and we don’t know what our pace was.
"Barcelona and Monaco should be better, so we have a few races to be excited about."
