Lewis Hamilton and his Mercedes team expect Max Verstappen and Red Bull to bounce back and give them a torrid test of speed at this weekend's Emilia Romagna Grand Prix, the second round of this year's world championship.
Three weeks on from the season-opening Bahrain Grand Prix, where Hamilton dug deep into his reserves to conjure up his record 96th Formula One victory ahead of the Dutchman, the seven-time champion knows it will be a challenge to repeat his 2020 win at the old Autodromo Enzo e Dino Ferrari.
Mercedes team boss Toto Wolff was delighted to see Hamilton triumph in the opener, but said Mercedes must still somehow match the superior speed of this season's Red Bull car.
"We may have won the first round, but we are under no illusions that this is going to be an easy season," he said.
"Our car still lacks speed on a single lap and Red Bull have the edge at the moment."
In Bahrain, Verstappen secured pole by three-tenths, but Hamilton made the most of strategy and race-craft to win, with the aid of a costly error by the Dutchman, by just seven-tenths of a second.
Hamilton's Bahrain victory showcased not only his speed, but his experience and supreme race-management, qualities that he will need again this season to fend off the challenge for his crown from Verstappen.
Hamilton rode his luck to win the 2020 Emilia Romagna race at Imola with some aplomb – and the help of a timely Safety Car intervention -- last November as he roared towards the drivers' title.
His win was the third triumph in a run of five as he took advantage of Mercedes' superiority and team-mate Valtteri Bottas's ill fortune to take command of the title race on the narrow and bumpy old track, back in use for the first time since 2006.
"Nothing changes," said Hamilton on Thursday as he looked ahead to facing Verstappen again.
"We approach each weekend in exactly the same way as in the past. It is exciting for us to have such a challenge."
Four-time world champion Sebastian Vettel summed up the Bahrain outcome.
"Max was faster but Lewis was smarter," said Aston Martin driver Vettel.
Hamilton made it plain last year that he loved the "old school" nature of the Imola circuit, set in the rolling vineyards of Emilia Romagna and Wolff shared his feelings.
"It's where won secured our seventh constructors championship that weekend," he said.
"And it's such an historic and iconic venue, which the drivers really enjoy – twisty and fast with a variety of corners."
Apart from Hamilton, only one other driver has previously won at Imola – two-time champion Fernando Alonso, who has returned to race for the Alpine-branded Renault team this year.
Alonso will be hunting an improvement on his pointless run in Bahrain, where he retired, as will fellow veteran and four-time champion Sebastian Vettel after a laboured first outing for Aston Martin.
Their experience may help at Imola, but it is likely to be Red Bull setting the pace in a thrilling duel with Mercedes – with McLaren, Ferrari and AlphaTauri in hot pursuit.
