McLaren group chairman and former team principal Ron Dennis has directed the team's drivers Lewis Hamilton and Jenson Button 'to stop whining and start winning' races.

The duo had complained about the pace of their cars this season.

"It builds the perception that we're giving them cars that are less capable of winning races," The Sun quoted Dennis, as saying.

"I do point out to them 'Well, I still think you won four races between the two of you. Aren't you leading the world championships?' It's the nature of drivers," he added. (ANI)
