Helmut Marko has commen𝔉ted on the ongoing struggles at rivals Mercedes.

The Red B🅷ull advisor has described his own surprise to see the once-dominant Me🎃rcedes fail to deliver a winning car for the third season in a row.

The W15 currently languishes behind Red ෴Bull, Ferrari 𒉰and McLaren.

M🍒arko was asked by : “As an outsider you get the feeling that Mercedes are still g🥀etting worse. Shouldn't all alarm bells be ringing?”

He replied: “They probably do anyway.

“What irritates me so much is that the car is real෴ly fast 🗹at times, and at times it runs at absolute peak times.

“Then I think: ‘Look, now they get it!’

“But that's always just a flash in the pan.”

Mercedes’ highs and lows were summed up 𒉰last weekend in Chin꧟a.

Lewis Hamilton emerged from༺ Friday’s qualifying for the sprint rac𝔍e insisting that the W15 “came alive” after his brilliant session in wet conditions.

Hamilton then claimed an encouraging P2 in the s🌞print race behind Max Verstappen.

But he 🃏made an error in qualifying for the grand prix, and explained “massive changes” in set-up from hi💫s earlier sessions.

Hamilton battled from 18th on the starting grid🐻 to P9 in a Chinese Grand Prixജ to forget.

“It d𒊎oesn’t happen overnight that you slu🅷mp like this,” Marko said.

“What is alarming is that they ha🍰ve not been competitive for the third season now.”

The tipping point was the 2021 Abu Dhabi🌳 Grand Prix, when Hamilton lost out on a record eighth title and Verstappen won his first for🍨 Red Bull.

Red Bull and Verstappen have dominated since, and the champion 🌞is on ꦡcourse for a fourth title in a row this year.

Hamilton, meanwhile, is battling through his final y♈ear at Mercedes before going to Ferrari.
