( 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 can not 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 does n't matter the talent , it does n'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 do n't think at the moment that this is clear for everybody . '' Alonso 's position at the head of the standings could not have been predicted at the start of this season , when he and his Italian team publicly doubted the race pace of the two Ferraris . `` We were not happy with the car at the beginning of the season . We were not rich with the expectations and the team tried to understand the problems as soon as possible and tried to make the changes , '' the 30-year-old said . `` They seemed to work but even if we are happy now with the position and with the points we achieved , we still know and are honest with ourselves knowing that we are not quick enough at the moment still . There is still plenty of work to do but we think a strong reaction is still to come from Ferrari . '' F1 teams battle from race to race to make minor adjustments which often have a big impact on performance , and Alonso gave credit to Ferrari 's technicians for improving the cars . `` We changed mainly aerodynamics . Formula One is dominated by aerodynamics and we had some areas of the car that were not working exactly as they were designed , so we did some tweaks there , '' he said . `` We changed some philosophies of working in the car and it started to work . But as I said it 's not enough , we know that and we will keep doing upgrades to the car . '' While Alonso has shown his ability in an underperforming car , teammate Felipe Massa is under increasing pressure to retain his place . The Brazilian , a world championship runner-up in 2008 , has recovered from serious head injuries suffered the following year but has very much been the number two driver since Alonso arrived from Renault in 2010 . `` We know that there has been some coincidences and some bad luck and moments in particular races that he did n't score points he deserved , '' Alonso said . `` We know that in practice and in qualifying we are much closer , we are fighting , we are together in some of the first corners , but then some factors make him always in some troubles , some incidents , and he lost points . `` But he has the talent , he has full support from our bosses , from me , from everybody in the team and we know the talent from Felipe . We know that before later he will shine . '' Alonso became F1 's youngest double world champion when he won back-to-back titles with Renault in 2005-06 , but he was usurped by Red Bull 's Sebastian Vettel last year . Now the German driver has been tipped to follow Alonso 's footsteps and join the most successful team in the sport 's history , reportedly in 2014 . `` ( It 's ) only speculation . Every year in Ferrari it is like this , '' Alonso said . `` I had this when I was with Renault in the past . Every year around summer always the speculations : 'Alonso will go to Ferrari . ' I answered many questions over the years and now when I joined Ferrari it is the opposite . `` Every year someone is coming to Ferrari , it has been like this . I think it is something you have to deal also when you are in Ferrari . '' Alonso is hoping , despite his car 's weaknesses , that he can deliver Ferrari 's first drivers ' title since Kimi Raikkonen in 2007 . `` Things are complex and not straightforward and I think it will be quite tight for the championship , '' said Alonso , who is 25 points ahead of Raikkonen , back on the grid this year with Lotus after a two-year absence . `` There is not one car dominating the season as we saw in the last couple of years . I think we will be there . I do n't know if we will be champions but we will fight until the last race , I am sure . ''
