Ferrari's Fernando Alonso has said he is not concerned about Red Bull Racing and that he is 'more or less confident' the Scuderia will have the best car in the next few races.

Alonso failed to finish the Malaysian Grand Prix last weekend after an engine problem sidelined him with the finish in sight. However while Sebastian Vettel and Mark Webber did take a dominant 1-2 finish for Red Bull, the Spaniard re-iterated that they had it easy at Sepang after Ferrari - and McLaren - made a mess of qualifying and misjudged the changeable weather conditions.

"They have three pole positions, but the three wins I'm not sure [they would have done that], because we were very quick in Bahrain and we were maybe quicker than them in Australia," Alonso told planet-f1.com. "Here it was a strange race, too easy for them because we made a mistake in qualifying. We are not too worried at the moment.

"It's a very long championship and we are capable of improving the car a lot. We know in which areas we need to improve the car, so I'm more or less confident that we can have the best car in the next few races.

"As always you need the consistency to be champion, but also you need to be fast. We are only in the third race so it's normal that the leader changes in the first races. You need a few races to settle down the championship.

"As usual, you need to finish all the races if possible and to take points, but also especially with the new points system you need to win races as well, because it's a good reward of 25 points.

"At the moment it's open with many drivers around 30 points. But as I said, when the championship goes to the end I'm sure only two or three drivers will fight for it."

As for his engine failure, Alonso continues to insist that it is not something that will keep him awake at night.

"It is not a concern, for sure. We had some problems - and for sure we will investigate it. But overall I think the engines are more or less the same as last year so I think our engine guys have a lot of experience with this engine without any problems," he added.

"I'm sure the problems we are having now are very specific thing that we will study after this race."
