The bet was made during last year’s silly season, when then Red Bull driver Ricciardo was considering his future options.
He believed that Valtteri Bottas would leave Mercedes, and Marko bet him that the Finn would stay with the Brackley team, which proved to be correct.
“He did win €1000,” said Ricciardo when asked by Motorsport.com about the bet. “He always wants to bet more – but when he wants to bet more, you know he already knows the answer!
“I’m not a gambling man, I don’t really bet or go to casinos. A thousand is not by choice, it’s a bit of peer pressure from Helmut.”
Renault driver Ricciardo stressed that having later won the money back, he’s not keen to enter into another bet with his former boss.
“We did another bet actually, I think it was in Melbourne, and I won it back. So we’re even. It was qualifying, he thought they would be top three in qualifying, and I thought they wouldn’t, and they weren’t, so I got my money back.
“I don’t want to bet with him anymore. But it’s OK, if our relationship is like that, it’s quite fun!”
