Lewis Hamilton admits McLaren are lagging "a long way away" from Red Bull Racing in terms of pace after being soundly beaten at the British Grand Prix.
Starting eighth on the grid, Hamilton had hoped to make amends for a poor qualifying performance at his home grand prix. However, instead he finished exactly where he started.
The McLaren driver opted for a long first stint that saw him leading the grand prix for several laps before his first pit stop dropped him well down the order.
Attempting to leapfrog rivals, Hamilton had a short middle stint of just eight laps on the soft Pirelli rubber before he was back in the pits for his second and last stop.
After 52 laps Hamilton finished down in eighth place, 36s behind race winner Mark Webber.
"We are a long way away (from Red Bull)," the 27-year-old told the BBC. "We will keep working at it and hopefully catch up.
"It was a disappointing day in the sense we wish we could have gone further forward and given more for the fans.
"I pushed as hard as I could but I didn't have any speed for some reason.
"You have to have a balance to make the tyres last, I think it was not so bad and I was in lead at one point but after that I did not have the pace.
"We thought we were going to be better but sadly not."
