(Mercedes AMG F1 Team)

It has been an absolutely MASSIVE day in the Formula One driver market with 2015 grid seemingly taking shape nicely. Hear is what he know for certain:

Mercedes AMG PETRONAS F1 Team have confirmed Nico Rosberg and Lewis Hamilton

Infiniti Red Bull Racing have confirmed Daniel Ricciardo  is likely to stay on and will be joined by Daniil Kvyat following an impressive rookie season with Toro Rosso for the Russian.

Ferrari have Kimi Raikkonen locked into a contract for 2015 with reigning world champion Sebastian Vettel likely to join the Finn at Maranello after confirming his departure from Infiniti Red Bull Racing this morning as he looks for a new challenge following four world title's with Red Bull Racing.

Williams Martini Racing confirmed Valtteri Bottas and Felipe Massa for 2015 on the morning of the Italian Grand Prix.Vettel seemingly 

McLaren who will have a 'works' engine partnership with Honda for next season have no drivers in place for next season. Jenson Button is out of contract with the team at the end of the season while they have an option on Kevin Magnussen however it is unclear whether this will be activated. With Vettel seemingly moving to Ferrari, Fernando Alonso has been cleared to move to McLaren. But who will partner the Spaniard? 

It is believed that Honda will be looking for experience during their first year back in Formula One which would make Jenson Button the most logical choice to for the team as he is the only driver on the grid at the moment who has experience working with the Japanese manufacturer. 

Ron Dennis, McLaren's CEO has not ruled anything out including keeping Button and Magnussen for next season.

Despite rumors linking Nico Hulkenberg to a move away from Formula One  to the World Endurance Championship the German has all but confirmed that he will remain with the Sahara Force India Formula One Team alongside Sergio Perez. next season. Team boss Dr Vijay Mallya took to Twitter following the Singapore Grand Prix last time out to say:

'Nico Hulkenberg drove fantastically to put us in the top ten points. Proves he is a reliable points scorer all season.'

Hulkenberg is currently in eighth place in the championship on 72 points. At the Lotus F1 Team, Pastor Maldonado is signed up for another year while Romain Grosjean looks likely to remain with the Enstone outfit for a fourth consecutive season despite an extremely tough 2014 campaign. The team are expected to confirm in the coming weeks that they will have a supply of Mercedes power units from next season onwards.

At Toro Rosso, Max Verstappen will make his full Formula One debut in Australia next March and in doing so will become the youngest Formula One driver in the history of the sport to enter a Grand Prix event at the age of 17. 

He is likely to be joined by a driver from Red Bull Young driver programme as Jean Eric Vergne had been replaced by the Dutch driver for next season. It is likely that Carlos Sainz Jnr or Antonio Felix Da Costa will be the candidates for the drive alongside Verstappen.

The situation at the Sauber F1 Team remains unclear as the Swiss based outfit have struggled this season and have failed to score point. It is increasingly likely that Adrian Sutil will be replaced at the team by either the team's Russian protege Sergey Siroktin of their test driver Giedo Van Der Garde while it is possible that Esteban Gutierrez will be retained for 2015.

The situation at the Caterham F1 Team is also unclear, however the outfit are hopeful that they will be able to retain Marcus Ericsson and could also retain Kamui Kobayashi. New team principal Manfredi Ravetto has confirmed that the team is financially healthy despite a visit from the bailiffs earlier this week however he insisted that this had nothing to do with the Formula One operation as if it had they would not have been taking part in tomorrow's Japanese Grand Prix.

He also revealed that the team will undergo a restructuring programme over the winter which he hopes will include moving out of their Leafield factory to another facility. 

Despite scoring two points this season at the Monaco Grand Prix in May, the Marussia F1 Team's future remains unclear with team president Graeme Lowdon revealing that the outfit will see out the rest of the 2014 season but beyond that he is unsure of what the future holds for the Banbury based outfit. 

Should the team remain on the grid in 2015 it is likely that they will retain Jules Biachi and Max Chilton, however it is also possible that they may choice to give test driver Alexander Rossi a race seat as he would have the potential to attract sponsors from the United States which would certainly help the team financially. 

WATCH THIS SPACE - THERE IS STILL PLENTY OF TWISTS AND TURNS TO COME AHEAD OF F1 2015.
