Kevin Magnussen says he has been approached by rival teams over a future race seat, though emphasies that his focus remains with McLaren.
Magnussen raced for McLaren in 2014 but was demoted to a reserve and test role after the squad hired Fernando Alonso to partner Jenson Button.
Magnussen replaced the injured Alonso for a pre-season test and the Australian Grand Prix, but has not tested a Formula 1 car since and his future remains unclear.
McLaren has yet to confirm its 2016 line-up, amid suggestions that it is weighing up whether to retain Button or promote Magnussen or GP2 championship leader Stoffel Vandoorne to partner Alonso.
Magnussen, 22, is nonetheless confident that he will be returning to a race seat in 2016.
"We can say other teams have reached out, it’s no secret. So I do think I still have a future," Magnussen told F1i.
"You can always talk to people. It is quite sensitive. Not many, but some interesting ones. There aren’t many Formula 1 teams available actually - some interesting ones.
"I obviously hope that I can continue my career with McLaren but that might not be possible and if it isn’t possible then I need to continue racing.
"I’m a racing driver and I need to race, that’s what I do. McLaren will understand and help me continue my career if there isn’t a space at McLaren. So I feel quite positive about my future."
