The former world rally champion Ari Vatanen's considering standing against Max Mosley if the Briton seeks re-election as president of motorsport's world governing body.
Mosley, who's 69, said last month he wouldn't seek a fifth four-year term of office in October as part of a deal with Formula One teams calling for a reform of the sport's governance and threatening a breakaway series.
Mosley since accused the teams of "dancing on his grave" suggesting he's under pressure from members of the Paris-based FIA to stay on.
Vatanen says Mosley's done a lot for motorsport, but he feels there's a time when every organisation needs change.
Mosley has been a controversial figure, most notably last year when he saw off calls for his resignation over a sado-masochistic sex scandal and then won a high court lawsuit for invasion of privacy.
