RedBull could face major threat next season

So with the news last week that Lewis Hamilton is moving to Mercedes next season and Sergio Perez is moving to McLaren the big question that I want to ask is, Will RedBull's recent dominance of Formula One continue to be challenged? The reigning champions are under pressure this season and find themselves leading the Constructors championship by only 36 points with 6 races to go.

The team appear to have really struggled this season with defending champion Sebastian Vettel on picking up his second this season last time out in Singapore. Meanwhile team mate Mark Webber has also picked up two win's. Vettel currently finds himself in second in the championship 29 points behind leader Fernando Alonso and only 16 points ahead of Kimi Raikkonen who is in third place.

I believe that Sebastian Vettel will not be successful in defending his driver's championship this year and I believe that he and team mate Mark Webber could struggle next season as in my opinion five team's will be challenging for the championship. Lotus, Ferrari, RedBull, McLaren and Mercedes should all be in a position to challenge for the title in 2013.

You make think I am crazy to include Mercedes in that list but with the team landing Lewis Hamilton to partner Nico Rosberg I believe that the team potentially have the ingredients to possibly repeat the success of their championship winning Brawn in 2009. Don't discount Kimi Raikkonen too, as if the Finn fails to win a GrandPrix this season you can be sure that he will return Lotus to the top step of the podium next season.

It is going to be extremely interesting to see what happens next season especially with McLaren, because despite the fact the focus has been on Hamilton moving to Merc, it has in my opinion almost been glossed over the fact that he is being replaced by one of the most exciting driver's in Formula One at the moment in Sergio Perez. When I look at what Perez has been able to do with the Sauber car that has been punching above it's weight all season I can't wait to see what he will be able to do with a car that is expected to be challenging at the front of the grid from the start of the season.
