Toto Wolff counters Max Verstappen and Lewis Hamilton F1 salary claims with US model offer

Mercedes chief Toto Wolff has backed a Formula One salary cap despite opposition from racers including Max Verstappen and Lewis Hamilton. The Austrian pointed to some American sports that have been successful after capping its stars' earnings.

Verstappen and Hamilton are the two biggest names in F1 and have spoken out against a salary cap, with the reigning world champion pointing out that drivers risk their lives to compete. The Dutchman recently signed a five-year extension worth a reported £43million per year.

F1 bosses have apparently discussed a salary cap amid continual limits on the spending teams can make. And Mercedes team principal Wolff has backed the proposals, insisting it is difficult to pay such salaries to drivers while team staff have a share of a smaller pot of cash.

"Certainly it has come up as a controversial topic. We can see we are facing a very difficult situation in Formula One overall, the sport is booming and Formula One is earning more money and that is trickling down to the teams, but we have a cost cap," he told journalists at the Azerbaijan Grand Prix, which Red Bull ace Verstappen won to extend his lead in the race for the drivers' world championship.

"We have $140million (£115m) for 1,000 people, with inflation - we haven't even been able to pay the inflation. And I think the talk about [even a] $30-40million (£24-32m) salary allowance is inadequate when you take that perspective.

"Now clearly drivers will have an opinion on that, and maybe as a driver I would say the same thing. But the US leagues that are the most successful in the world introduced salary caps 15 years ago. It works pretty well over there."
