Mercedes motorsport boss Toto Wolff believes Nico Rosberg and Lewis Hamilton will once again push each other all way in the battle for this year's title.
The 2014 Drivers' Championship was decided at the final race in Abu Dhabi with Hamilton walking away with the crown, and if recent events are anything to go by then we are in for another close battle.
Hamilton started the season in excellent form as he won three of the first four races, but Rosberg has turned things around as he has won three of the last four races to reduce the gap in the standings to just 10 points.
Wolff says the two drivers are pushing each other on.
"Most of the time they were under pressure because they kept pushing each other, we saw that in qualifying and then he [Rosberg] was faultless on Sunday and had great speed during the race. I would just say he has that strength and it's going to go down to the wire," the Austrian said.
In the battle or pole position on Saturday, both drivers made mistakes on their final flying laps and went off track.
Wolff added: "I don't think they are feeling the pressure of the overall Championship yet.
"They are definitely pushing very hard in order to beat each other and you rarely see someone coming with the locked, smoking wheels into the stands, because you could well miss the line and get a penalty and equally on the exit. It's just the result of a very fierce battle between them."
