"Have a tea break!" Hamilton's radio jab doesn't expose a rift in the team, but there is a growing sense of urgency

Lewis Hamilton has revealed that he had to tell Ferrari boss Fred Vasseur to 'calm down', after some tense moments with the F1 team during the Miami Grand Prix. Having set the fastest lap of the race on his new medium tyres, Hamilton asked the team to let him past team-mate Charles Leclerc so that he could chase after Mercedes ' Kimi Antonelli.
