Renault team boss Flavio Briatore has dismissed suggestions that Sunday's title-deciding Brazilian Grand Prix could be overshadowed by dirty tricks.
Alonso will be hoping to celebrate in Brazil on Sunday
Fernando Alonso needs just one point to win the drivers' championship ahead of Ferrari's Michael Schumacher.
And Briatore insists the German's history of on-track collisions should be of no concern to Alonso.
"Michael is very professional and if he is involved in any accidents, then he loses the title anyway," he said.
Crucial championship races involving Schumacher have been marred by crashes in the past, most notably involving Briton Damon Hill in 1994 and Jacques Villeneuve in 1997.
Until the final lap, when you know you are champion, anything can still happen and we are taking nothing for granted
But Briatore is confident that Schumacher will abide by the rules in Brazil, saying: "I really don't have this kind of concern because Michael wants to leave Formula One in the right way.
"I know Michael very well and I don't think there is a problem. It's good for the press talking about that, good for the gossip and the newspapers, but it will be a normal, fair race."
And, despite his 10-point lead, defending champion Alonso insists the championship is not over yet.
"I don't think it is over at all. Until the final lap, when you know you are champion, anything can still happen and we are taking nothing for granted," said the Spaniard.
"Our aim has to be to do a normal weekend, to get the maximum from the car without any big risks, and to finish the job."
Schumacher, who has publicly written off his chances of overhauling Alonso's lead, says he is concentrating on helping Ferrari win the constructors' championship.
Renault lead Ferrari by nine points in the race for the team title but Schumacher, who is retiring at the end of the season, said: "We will go on the full offensive and want a one-two because the boys deserve this title.
"That is the only chance we have to win and that is all that we can do. The constructors' championship would be fully deserved in my eyes.
"I am aware that after nearly 16 years this will be my last race. It goes without saying that I want to end with a good one."
Renault have agreed a three-year title partnership with Dutch banking giant ING, ending tobacco brand Mild Seven's long-running association with the team.
The outfit will be known as the ING Renault F1 Team from the beginning of the 2007 season, meaning that the title-deciding Brazilian Grand Prix will be the last featuring Japan Tobacco's colours.
