Alonso certain his situation will improve

Alonso told Spanish radio earlier this week that he was not 'totally comfortable' at McLaren after feeling that the support from the team was going towards Lewis Hamilton.

Speaking to reporters at Indianapolis ahead of this weekend's United States Grand Prix, Alonso stood by his comments but insisted that they were not intended as criticism of McLaren.

"I am happy; I am happy with everything," he said. "My life is fantastic, and with the team as well.

"I know that this week has been quite difficult after the comments in Spain, but I think those comments are quite normal. I said that I am not totally comfortable with the team, and I understand completely the position. But there are no complaints."

Alonso believes that improvements to help him feel better at McLaren can be made by both himself and the team.

"Sure with the tyres and with the car I need to improve, I need to feel more comfortable because it has been a big change for me moving teams.

"And with everything, with the team as well, it is a completely new team, a new approach to the races and a new philosophy as well. Sometimes it is not easy to get used to things in a very short time."

Alonso said he has raised the issues he has with the team and believed the situation would improve in the future.

"I think it will come with time. I hope so because, as I said, the philosophy of the team is clear. It has been always like this for the past. I think we all need to accommodate ourselves in the new position."

Despite the situation, Alonso is adamant that he still has a better chance of winning the world championship this year than at any previous point of his career.

The Spaniard is currently eight points behind teammate Lewis Hamilton, but is convinced that he is better placed to end the year as champion than he was even during his successful campaigns with Renault.

"I want to win this year's championship and I am 100 percent confident that I can do it because I have a fantastic car, and a fantastic team behind me as well," said Alonso.

"I can do it even with more possibilities than the previous years that I had to fight with a very strong McLaren in 2005, and with (Michael) Schumacher last year. So it was quite a tough championship, quite a difficult championship and this one will be quite difficult. But I do really think that I can do it."

Alonso still thinks the title fight is a four-way battle between himself and Hamilton, plus the two Ferrari drivers of Kimi Raikkonen and Felipe Massa.

"I think at the moment both will be contenders I think," said Alonso when asked whether his biggest threat for the title came from teammate Hamilton or Ferrari.

"We saw from the beginning of the season Ferrari and McLaren dominating the races and all four drivers can win races and can win the championship.

"It is true that we were very close in points three or four races ago. Now we start to open a gap between the first and the second guy, the second and the third guy, and the third and the fourth guy.

"So if this continues for three or four races, then probably the fourth guy will be in trouble. Maybe then the third guy will be in trouble and then maybe it is between two or three of us. At the moment, after six races, I think all four drivers still have the big possibility."

Alonso says that a podium finish in Indianapolis this weekend will mean a lot to him, because of the struggles he has had at this track in the past.

"It will be a better race this one, hopefully, for me," he said. "It is good fun to come here again. I have never had good results here in Indy, so I really am quite focused on this race.

"It is one of the most important races for me this one if I can score a podium, because it is probably the only trophy that I miss in the collection."
