Carlos Sainz has urged his bosses at Toro Rosso to let him and teammate Max Verstappen race more freely this season than they did last year in their rookie year.
Last year, as the young duo made their impressive F1 debuts, team engineers were often heard instructing the Spaniard and Dutchman to let the other pass.
"It was common to hear the message 'Let him past' when the other is getting close," Sainz told Auto Motor und Sport.
At one stage during the season, Verstappen memorably screamed "No!" when instructed to let his teammate go ahead.
Sainz said: "I think it would be fun if we could fight more often against each other. We have good respect for each other and it would be an exciting show because our pace is very similar."
