MONACO, June 7 (Reuters) - ⁠Four-time world champion Max Verstappen's Monaco ⁠Grand Prix lasted one slow lap as ‌the Red Bull driver retired with a power unit problem on Sunday.

The Dutchman produced a brilliant qualifying session ​on Saturday to line up ⁠alongside Mercedes pole ⁠setter Kimi Antonelli on the grid, but as ⁠the ‌red lights went out at the start his car remained stationary.

Verstappen did ⁠manage to get away but limped around ​the ‌circuit at slow speed before his team ⁠told him ​to "bring it home" and he returned to the garage.

"The formation lap wasn't going very well, ⁠after that the pre-start was terrible, ​there was no consistency and then the engine just dropped dead," he told Sky Sports.

"I ⁠only got a little bit of power back after the first corner. Engine sounded really awful, couldn't go full throttle so we ​brought it back."

It continued a ⁠miserable season for Verstappen, who has voiced ​his disapproval of the new ‌hybrid engine regulations and ​has even threatened to quit the sport.
