Martin Whitmarsh sounded unimpressed with the stewards’ decision not to penalise Felipe Massa after qualifying for the Monaco grand prix.
McLaren driver Button was unhappy with the Brazilian for blocking him towards the end of a flying lap in Q3.
"On top of that the next timed lap was destroyed as well, because I had a bad run onto the pit straight," said the Briton, who qualified.
It had been expected that the stewards would penalise Massa, but the Ferrari driver insisted: "I didn’t hold up Jenson. We were in the last corner and there was a car in front of me."
McLaren team boss Whitmarsh confirmed that the stewards decided not to penalise Massa.
"The stewards decided Massa did his best to get out of Jenson’s way," he is quoted by the Daily Mail. "On this occasion, his best wasn’t good enough."
