Martin Brundle feels that Lewis Hamilton will find things tough if Mercedes cannot find the pace to match Max Verstappen and Red Bull.
Mercedes are on a streak of five races without a pole position or win, something which has not happened since 2013 whilst Red Bull have won each race during the same period.
"I think Lewis will struggle if he looks at the rest of this season thinking 'I just don't have the speed in the car to match Red Bull'," Brundle told Sky Sports.
"I'm sure they [Mercedes] will be trying to finesse the car. Red Bull have done that to theirs. But with the cost caps now, with the resources the teams have, and the dramatically new 2022 cars, they need to keep working on that because that car will be homologated and that will be in play for a number of years."
Brundle referred to the difficult decision that the top teams especially are having to deal with. Many teams have stopped working on this year's cars to focus on their 2022 machines when F1 introduces a new set of technical regulations which could shake-up the pecking order.
Mercedes confirmed they will bring upgrades to the British Grand Prix whilst Red Bull have stated that they will end development after the Hungarian GP which leads into the summer break.
"Get the 2022 car wrong, and you will take pain for two or three seasons," said Brundle. You can't take that gamble.
"I think Mercedes will have to go right, 'we've got a few tweaks to this one, then we'll call it off and see what happens on strategy, weather, luck, whatever'."
