Felipe Nasr has not denied reports that he is on the search for an alternative team for the 2017 season.

Frustrated with stalled car development and worrying financial problems, the Brazilian driver and teammate Marcus Ericsson incurred boss Monisha Kaltenborn's wrath in Monaco when they collided.

It preceded reports that Nasr could leave the Swiss team at the end of the year, given that his and his sponsor Banco do Brazil's sponsors with Sauber are expiring.

Nasr, 23, is not denying that speculation.

"Since I came into F1 I had many dreams I wanted to achieve and I still do," he is quoted as saying by Brazil's Globo.

"I do not want to let my opportunities pass. I can assure you that I have good people working on it so that we can take the next step in considering all possible options for 2017, even if it's too early for anything right now.

"I think that from the middle of the year we will start talking to know what options there are, but what I can say is that we have options. More than one."

The newspaper also reports that better times for the team could be around the corner, with car improvements planned for Silverstone in July.

"The priority is the aerodynamics," said Nasr. "We have very little downforce in the car, which creates instability.

"Gaining performance in braking and traction will all be with improved aerodynamics, not to mention that we will also have an update of the entire [Ferrari] drive train."

Currently, Nasr and his teammate Ericsson have not scored a single point between them in 2016.

Nasr said: "I will do everything to score a point and I think it would be almost a victory for us. But it's just the situation we are in at the moment."

Next up on the calendar is this Sunday's Canadian Grand Prix.
