Sebastian Vettel has suggested that he will have a greater say in team affairs at Ferrari next season.

The German joined the Scuderia from Red Bull and has won three grands prix in his first season, but has not been able to maintain a serious title challenge against the Mercedes pair of Lewis Hamilton and Nico Rosberg.

However, Vettel is hoping for a "big step" from Ferrari in 2016.

He is quoted by Crash.net as saying: "You don't join the team until you join the team, so a lot of decisions had already been taken, so were taken when I was there already.

"[But] the season we have had so far has been phenomenal when you consider where the team was last year and the situation that we faced at the beginning with a lot of new people, a lot of change of position in the factory. Not that easy to digest for a team, but it has been great.

"Really strong getting the team together, so I am quite confident and hope that next year is a big step."

Vettel crashed out of last weekend's Mexican Grand Prix, which was won by Rosberg.
