Alonso worries about his Formula One future

By Alan Baldwin

MONACO (Reuters) - Double world champion Fernando Alonso feared for his future on Wednesday with Renault and Ferrari threatening to quit Formula One if the 2010 regulations are not rewritten.

"Here... I will be 100 percent focused on the grand prix, with the weekend," the Spaniard, who has been regularly linked with a move to Ferrari from Renault, told reporters at the Monaco Grand Prix.

"But it is true that last week when I was at home it was impossible to switch off because I don't know if this will be my last time in Monaco.

"If the big teams and the big manufacturers leave Formula One then I don't want to race with small teams, because it is not any more F1 and there are many other categories," added the 27-year-old.

The governing International Automobile Federation (FIA) has put forward an optional 40 million pound ($61.93 million) budget cap for 2010 with those accepting it offered greater technical freedom than teams staying with unrestricted budgets.

NO TIERS

Although FIA president Max Mosley has said there will not be a two-tier championship, with all teams expected to race with a cap, champions Ferrari have said they cannot accept the regulations.
