Negotiations between Fernando Alonso and Renault about 2008 have reached a deadlock, reports from Spain and Italy on Tuesday said.

The Spanish sports daily Marca claims that while team boss Flavio Briatore is happy to accept Alonso's demands for a one-year contract, Renault CEO Carlos Ghosn is refusing to budge on the offer of a minimally three-year stay.

It is rumoured that Alonso wants a one year deal because he has already agreed to switch to Ferrari in 2009; a scenario that might understandably be unattractive to Renault chiefs.

The wire service Agenzia Giornalistica Italia (AGI) quotes Ghosn as confirming: "It's three years or nothing." (GMM)
