Traffic and a basic lack of pace were to blame for a less than fulfilling Spanish Grand Prix at the Circuit de Catalunya on Sunday for McLaren driver Jenson Button.
"I'm usually very good at looking after tyres and have a pretty good consistency" said Button after the race in Barcelona. "That's something I always work on.
"Can't do that at the moment and I don't know why," he continued. "I'm really struggling with the car - and it's not an overnight fix, which is a little bit worry as I really don't know why it's not working here," he warned.
The first two races were great in terms of race pace and qualifying," he added. "But Bahrain was tricky and here was also tricky. The balance - it's not just one end, it's both ends, I just can't find grip and I can't use it.
"All in all, we weren't quite quick enough today – but that's something I need to solve myself. I need to find a set-up that suits me better as I feel like I have pretty poor grip at the moment."
Button got a wake-up call when he got barged aside by a typically bold manoeuvre from Kamui Kobayashi going into turn 5 on lap 34: "A lot of my afternoon was spent stuck in traffic," he agreed. "I had a Sauber breathing down my neck for most of the race."
However, he did manage to use his DRS to good effect to blast past the Ferrari of Felipe Massa at the end of the start-finish straight on lap 42, after the Brazilian had earlier frustrated Button's team mate Lewis Hamilton for an extended period.
"The F1 form book is very mixed-up at the moment, which is unusual, but that's the way it appears to be going this season," said Button.
"I'm already looking forward to Monaco and a much better weekend there," he added. It's a circuit I love and hopefully a place where we can achieve a good result."
McLaren team principal Martin Whitmarsh could tell just how disappointed Button was with how Spain had turned out.
"He struggled with balance and grip all afternoon, and won't be satisfied with the brace of world championship points that his ninth place delivered him," said Whitmarsh.
Looking ahead to the next race, Whitmarsh pointed out that Button - like his team mate - is a former winner in Monaco.
"He'll approach the dauntingly tortuous streets of the famous principality with the forceful precision that marks out both our drivers as the superb world Champions that they are," he said. "They'll both be aiming to win, of that you may be sure."
