Sebastian Vettel believes that the dominance of Mercedes can come to an end despite the silver arrows recording a fifth-straight victory of the season in Catalunya.
Vettel enjoyed a successful race weekend in Spain, from having to start back in 15th place on the grid, the German displayed the driving ability we have come to expect over the last four years as he made his way up to finish in fourth.
"We are here to fight for the championship," said Vettel who completed the fastest lap of the race.
"Hopefully in time we can catch up and give them a run for their money.
"They deserve to be in that position, but from our point of view we hope that their dominance can come to an end."
However, there can be no denying the task which is ahead for the 26-year-old who finished one minute and 16 seconds adrift of Hamilton out in front.
"I enjoyed the race and third and fourth is the best we could get," Vettel added.
"Mercedes is very strong, they have a phenomenal engine, a very good car and two very good drivers."
Vettel's team-mate Daniel Ricciardo finished third in the race and remained upbeat about the rest of the season, putting faith in the quality of the team around him.
"It is a massive gap but I am sure we will get there. We all know what Adrian Newey is like, as well as the 600 other people at the team."
The Mercedes cars have been in the lead of every lap of the 2014 season which is now five races old, with four one-two finishes. They are in an exceptionally strong position in the constructors' championship with 197-points, 113 more than the Red Bull team in second.
But with 14 race weekends still remaining in the season it is far from over and there could be many twists and turns to come. With Monaco the next Grand Prix in just under two weeks time it is an opportunity to gain on the Mercedes team with the unpredictability of the street circuit.
It will be for certain that Red Bull are pouring money into developing this car and it would not be at all surprising to see it winning races by the end of the season. Especially with the much-wanted services of Adrian Newey involved.
What is apparent at Red Bull is they have themselves one of the strongest driver line-ups in the field. Sebastian Vettel is a four-time world champion and his new team-mate Daniel Ricciardo has taken to life with the constructors' champions with ease.
He looks remarkably comfortable and has delivered some impressive performances, giving Vettel a real problem by finishing above him in the last three races.
But it is Sebastian Vettel who is ahead in the drivers standings in the inter-team battle with 45-points compared to Ricciardo's 39. The pair will continue their duel in Monaco where Vettel has taken victory before in the 2011 season.
It was the Mercedes cars which were in charge again last year however, with Nico Rosberg taking victory from Lewis Hamilton. A repeat of that result would not be a surprise but the Red Bull's will be there looking to pounce on any mistakes.
