Ferrari team principal Stefano Domenicali has refused to comment on speculation that former Lotus technical director James Allison is definitely headed to Ferrari.
"It is a topic covered by a lot of rumours," team boss Domenicali is quoted by Russia's Formula 1news.ru website, "so I will not make a comment."
The Italian was also asked about Ferrari's likely engine customers for the 2014 season, amid reports that the Maranello team will replace its lost client Toro Rosso with Marussia.
The other currently Ferrari-powered team is the financially embattled Sauber.
"Very soon we will make the announcements," Domenicali said. "We will supply engines to two [customer] teams." (GMM)
