Daniel Ricciardo is calling for cool reflection in his RB Formula 1 outfit after a first-race blow-up with his teammate Yuki Tsunoda in Bahrain.

As three-time world champion Max Verstappen romped to a second straight season-opening win, Ricciardo was back in 13th and left raging at Tsunoda after a late-race incident that prompted him to fume over the radio to his team engineer about the Japanese driver.

Tensions had boiled over at Red Bull's junior team RB after a driver position-swap order from the team which left Tsunoda complaining, "are you kidding me?"

After delaying for a lap before giving way to Ricciardo, whose car was on the faster soft tyres, Tsunoda bemoaned "he's got to speed up, he's not fast at all" during the race.

He then showed his angry disapproval on the post-race cool-down lap when he sped past the Aussie's car on the outside, narrowly avoiding a collision.

It prompted Ricciardo to complain: "What the f***! I'll save it … f***ing helmet!"

Later, with tempers cooled, 34-year-old Ricciardo, who is in his 14th season as an F1 driver compared to Tsunoda's fourth, chose his words carefully but was clearly baffled by the 23-year-old's post-race antics.

"I don't know [what he was doing]. I came on the radio and I was trying to stay cool," Ricciardo told F1TV.

"He's obviously frustrated with the team orders but, let's be real, this is something we talked about before the race.
