F1 hopeful Dani Clos is set to bank EUR 1 million of his budget towards making his Grand Prix debut next season.
The 24 Chasa newspaper said well-known retired Bulgarian footballer Hristo Stoichkov has pledged the money due to Spanish GP2 driver Clos being his future son-in-law.
Clos is reportedly engaged to Stoichkov's daughter Mihaela.
A report by the Sofia news agency Novinite said Stoichkov is also lobbying his friends to invest in Clos' F1 tilt.
Clos has previously tested with the Williams team.
