McClaren team principal Martin Whitmarsh has taken responsibility for Jenson Button's poor showing at the Canadian Grand Prix in Montreal last weekend, blaming the team's strategy with the Pirelli tyres.
Hopes had been high of Button enjoying success at the event, following his win on the track last year.
However, this time round it proved to be a different story, with the Englishman struggling throughout the race before eventually finishing a disappointing 16th.
But despite the poor result, Mr Whitmarsh refused to be critical of the driver, instead pointing the finger firmly at himself and the McLaren team.
"Jenson is a great racing driver and we served him badly this weekend," he told Autosport.
"His rear tyres were completely shot. We didn't long-run with this suspension set-up on Friday and that was our fault – as we didn't give him a race car he could perform in."
Button is now eighth in the World Championship standings with 45 points from the first seven races and there are 43 points between himself and leader Lewis Hamilton.
