After Red Bull decided to retain Daniil Kvyat for 2017, development driver Pierre Gasly expressed his disappointed and revealed he will explore his options in order to get a drive for 2017.
The Italian-based outfit decided to keep their Russian driver despite being dropped by the Red Bull senior team and poor performances, which came as a surprise to many, including the Frenchman, who thought he would be racing for Toro Rosso next year.
"The target for me of course was to get in Toro Rosso next year," he told Autosport.
"I didn't actually understand their decision and I didn't get any reasons as well.
"It was kind of looking good for me, talking about it with [Red Bull motorsport advisor] Helmut [Marko] and trying to make it.
"Then I don't know what has happened as in two or three days, everything went so quickly. They signed Kvyat.
"I didn't understand it. It looked like I was in the right place but in the wrong moment pretty much from what I understood."
With race seats available at Force India, Sauber and Manor, Gasly admitted that he will be weighing up his options.
"I'm really disappointed by it, but now it is done and I need to move forward. I'm already looking at the future," he continued.
"Right now, it's quite wide open still in terms of options – you still have many seats left in Formula 1.
"I've talked quite a lot with Helmut this weekend and he knows my target, that I want to make it into Formula 1.
"We just need to find the best option, the best package, either in F1 or if we can't make it in F1 next year, I do something good to get myself ready for 2018."
