Jenson Button admitted that he needs to address his own performances as well as counting on McLaren to improve its car after a disappointing United States Grand Prix.
Button was hampered by first-lap contact for a second successive race, this time running into Felipe Massa.
He had to grapple with front wing damage thereafter, but did salvage a point for 10th place.
"I hit someone on the first lap again so I broke my front wing," said Button.
"It wasn't quite as bad as last time, but I lost a whole front left bargeboard.
"When you lose a bit of front wing, you lose the aero down the car."
"It's not just that [the car is uncompetitive]," he said.
"This weekend I just didn't put it all together.
"I've got to sort myself out."
Button was able to get up to 10th with a late charge that took him past Daniel Ricciardo's Toro Rosso with just two laps to go, after earlier attempts to progress via strategy failed.
"We pitted very early to at least try to jump people, but they just pitted on the next lap and we were still behind them," said Button.
"I knew I could look after the tyres better and have a go at the end."
