Ferrari's Michael Schumacher denied dirty tricks on Saturday after securing a Monaco Grand Prix pole that prompted rivals to question his sportsmanship.
The seven times champion stalled his car at the penultimate corner in the dying seconds of qualifying, preventing Renault's world champion Fernando Alonso and others from going faster.
Race stewards immediately called Schumacher in to explain his driving. A Renault spokesman said the team had not made a formal protest because an investigation was already in process.
Alonso, who leads Schumacher in the title standings by 15 points, was forced to slow on his final lap, losing at least three tenths of a second that would have put him on pole.
"I have my opinion and I won't tell it here," said the 24-year-old Spaniard when asked by reporters whether he considered it a sporting incident.
His team boss Flavio Briatore, who steered Schumacher to his first two titles at Benetton, had no such inhibitions.
"I think he is taking everyone for a ride," he told reporters. "Someone who was seven times a world champion wants us to believe that he didn't do it on purpose, it's fairyland.
"Whatever you do in certain moments, your enemies believe one thing and the people who support you believe another," he added. "Some people may not believe it, but unfortunately that's the world we live in.
"I don't care what other teams do. I know Flavio well enough," added Schumacher, who drove for the Italian when he was at Benetton.
The pole, if upheld, will be Schumacher's 67th of his career and third of the season.
