Despondent Lewis Hamilton believes McLaren need to “go back to the drawing board” after their disappointing performance in Bahrain on Sunday.
After two poor pit stops, Hamilton could only manage to finish eighth and has lost his place at the top of this year’s championship.
Reigning title holder Sebastian Vettel secured his first win of the season and 21st of his Formula One career to move back to the top of the standings, with Hamilton now four points back.
To make matters worse for McLaren, Hamilton’s team-mate Jensen Button was forced to retire a lap from the end of the race to cap a miserable day for the outfit.
Now, with gap of nearly three weeks until the next race in Barcelona and a three-day test session scheduled for Mugello next week, Hamilton is hopeful that they can put things right.
"I struggled with pace, with Sebastian pulling away at a second a lap, struggled with looking after the tyres. I just wasn't quick at all," he said.
"I still think I could have got fourth or fifth, but to end up eighth after two poor pitstops is disappointing. "The only positive is that I scored four points, but overall there aren't a lot of positives to take.
"We have to go back to the drawing board and try and figure out where we are losing time, because we are quick in qualifying. But something changes in the race, so we have to go back and work harder at the factory, and if anyone can fix it, it's us.
"I'm sure everyone's frustrated, so we have to look on the bright side and keep positive."
