Having dominated the early part of the season, Lewis Hamilton now leads team-mate Nico Rosberg by just 10 points after a dramatic Monaco Grand Prix.
Rosberg swept to victory in F1's marquee event after Hamilton's charge to victory was thrown off course by a major strategic error.
While the Mercedes team profusely apologised to Hamilton post-race, the driver admitted he had played a part in the call to pit, believing those behind would stop too.
The blunder handed Rosberg a third consecutive Monaco win and the first back-to-back race wins of his career, having triumphed two weeks earlier in Spain.
