Jenson Button says his problems with the McLaren will not be solved overnight after finishing ninth at Barcelona.
Button started in 10th position, but finished behind Lewis Hamilton, who started from the back of the grid after being penalized for not having enough fuel during his final qualifying run. The Englishman was unable to match the speed of his teammate and has complained of a lack of balance and ultimate pace throughout the weekend.
"The last few races the pace has been very good in the race but I really struggled with the car itself. It is not just one end, I felt that I just had very low grip," he said.
"I am normally good at looking after tires and having a good consistency, it is something I always work on but I can't do that at the moment and I don't know why. I am really struggling with the car at the moment. It is not an overnight fix."
Button was initially confident that he could get a good result in Spain after working on his long run pace, but was unable to get the McLaren to work in traffic.
"It is surprising with long run pace because that is something I always work very hard on so we need to look at the consistency for next race and try and work out why I can't work with these tires," he said. "I thought we were on for a better result than that. I am alright in clear air but then as soon as I am in traffic I can't keep any heat in the tires. I don't know why that is, I turn the steering wheel like everyone else does but it doesn't seem like that at the moment."
