Ferrari boss rules out Alonso-Raikkonen line-up

"To line up a Raikkonen-Alonso double act would mean wanting to damage yourself. I want two equal drivers that work together," the president told Tuesday's Gazzetta dello Sport daily.

 Alonso, now back at Renault with whom he won the drivers' championship in 2005 and 2006, is seen as a potential Ferrari signing next year.

 A stuttering start to the season by Ferrari's Felipe Massa has fuelled speculation of the Spaniard joining next season, although the Brazilian has a contract with the Italian team until 2010.

 However, Massa bounced back by winning the last Grand Prix, in Bahrain.

 Alonso, who goes into a home race at the Spanish Grand Prix in Barcelona on Sunday, recently denied he had a get-out clause at Renault if the French team proved to be uncompetitive.

 However he did say contracts were "very flexible" given his exit from McLaren Mercedes last year after just one season.
