A frustrated Lewis Hamilton questioned his Mercedes team’s strategy after he finished sixth behind team-mate George Russell at the  Miami Grand Prix.

After the fifth race of the year, Hamilton is sixth in the drivers' standings on 36 points, with fellow Briton fourth on 59.

The seven-time world champion said he was surprised to be asked if he wanted to pit for fresh tyres during a Safety Car period

"I really don’t know, in that scenario I have no clue where everyone is," he explained when asked about the incident.

He had finished a forlorn 13th two weeks previously at the Emilia Romagna Grand Prix.

Team-mate Russell made the most of the Safety Car to pit for fresh tyres  and, with that advantage, was able to pass Hamilton to finish fifth.

Ferrari’s Charles Leclerc leads the title race with 104 ahead of world champion Verstappen of Red Bull on 85.
