Kimi Raikkonen is certain he has the speed to compete at the top level in Formula One and is hoping his poor run of results will not affect his future at Ferrari.

Raikkonen has scored just four points in the last three races while team-mate Sebastian Vettel has scored 52. However, Raikkonen was stripped of a likely second place at the Hungarian Grand Prix on Sunday when his MGU-K failed and has struggled with a number of problems and glitches over the course of the season.

His contract has not yet been renewed for 2016, but Raikkonen is hoping Ferrari take into account the potential results he could have scored rather than just look at his position in the standings.

"People can look at it two ways, they can look that we did well or they can just look at the result. It depends which way you look, I feel that we have the speed and we have a lot of things that just keep going against us. It doesn't look great but there are a lot of positive things and obviously when we have issues it's not great. Obviously we have to somehow change that and we still have a great team capable of great results, but we have to finish the race first."

Raikkonen is sure he still has the speed to compete in F1 at the highest level.

"I've had some disappointments last year and this year and I'm sure this year we have had good speed all the time and we just kept having these issues here and there and a mistake here and there. It has shown the wrong results because of those, but if I didn't have the speed I would not believe in myself. I would stop if I didn't feel I had the speed or the passion. I would not come here, I would stay home. We have the speed but we've just had issues here and there and we've learned from mistakes."

Raikkonen believes the key to success will be ruling out the minor issues in the second half of the season.

"If it takes a long time then it's not such a great thing, but it's been far away from disaster and better than last year, so even if there are some problems and mistakes we will keep pushing and hopefully with a little bit of luck we can achieve great results and great races, but we just have to make sure we don't have any issues in any part of the weekend.

"I think that's the key point for us and we have been working on that to improve, but even this weekend we have had problems and even though we are doing things better and better as a team, things go wrong sometimes.

"When it goes wrong with us, with the car or with me, it is just the end result is not good. It's part of the game, an unfortunate thing and not a nice thing to have but what can you do? We will keep trying and I'm sure it will turn out to be good at some point this year and who knows what happens next year. It's not in my hands, it's in the teams, so let's see."
