American chain Subway could be the next sponsor to enter formula one, according to F1 business journalist Christian Sylt.
Zak Brown, an F1 sponsorship guru who manages the sandwich giant's motor sport portfolio, told the Telegraph newspaper that F1 and Subway are a "perfect fit".
"I took the Subway chief marketing officer to meet Bernie Ecclestone in Montreal last year, and I would say they have been exploring it for a year," said Brown.
"They (Subway) are all about the consumer, they are massive media buyers so they would look at a sport and see if it stacks up from a media point of view and formula one does," he added.
Brown suggested that, for its F1 foray, Subway could emulate its Nascar strategy in sponsoring "a team, an event and a driver".
