(CNN) -- Ferrari driver Fernando Alonso fears Formula One is in danger of becoming a "lottery" and says it could lose its credibility.
This season has produced six different winners in six races and, while conceding this was good for spectators, the two-time world champion told CNN it had produced disquiet in the F1 paddock.
"It's a fantastic season, it's so unpredictable. I think people stand in front of the TV, with some surprises every race. It's good for the audience, it's good for the sport to bring attention to the races," said the Spaniard, who leads the world championship by three points, with 14 rounds remaining.
"On the other hand we can lose credibility. We cannot lose that the best teams, the best drivers, the best strategies win the races, because at the moment from the outside it seems that in every race anyone can win.
"It doesn't matter the talent, it doesn't matter the team, the performance -- it's like a lottery. What you achieve in Formula One is not by chance. We need to make clear that if you win a race, it's because you did something better. And I don't think at the moment that this is clear for everybody."
