Fernando Alonso believes world champion Lewis Hamilton is the only one of F1 2018's drivers who can be truly happy at the end of the season.

Two-time champion Alonso, whose 17-year F1 career ends at the Abu Dhabi GP on Sunday, has faced repeated accusations over recent seasons that bad decision-making has cost him further success in the sport.

But Alonso insists he has no regrets about his career and points out there are many highly-talented drivers on the grid who have not even achieved his level of success yet.

Fernando Alonso leaves F1: What made him so good?

"In Formula 1 there is always one winning and all the others are not winning," said Alonso after his final qualifying session.

"Only one is happy here which is Lewis Hamilton this year.

"To finish second, seventh, 12th, it's the same. I won two championships, 97 podiums and I have mates here with a lot of talent like Nico Hulkenberg, zero podiums.

"Sebastian [Vettel] a lot of years now not winning.

"Verstappen, a great talent, zero titles.

"Ricciardo, a great talent, zero titles.

"They are all unlucky? Probably, but this is the way it is in sport and Formula 1. With all those things, coming from the north of Spain, go-karting guy, two-times world champion, no regrets on anything."

Alonso's two most recent career moves - his arrival at Ferrari in 2010 and then his departure to McLaren in 2015 - have often proved central to the debate about his decisions.

But the Spaniard believes few, if any drivers, would have turned up the same opportunities at the time.

"In my career I feel extremely proud to have driven for Renault, McLaren and Ferrari," he said. "They are the three teams that I spent 17 years of my career and probably, arguably, are the three teams with more wins and success in Formula 1. Now recently Mercedes has been dominating, but from my time I'm extremely proud of those three families I joined.

"I have been unlucky in some of the places that I have raced but without a crystal ball it's probably difficult to make decisions. After you finish your chapter it's easy to say, but when I joined Ferrari in 2010, I think 10 of 10 would have joined Ferrari in 2010 not another team.

"When I joined McLaren-Honda in 2015, all of 2014 I had been hearing it was a very good decision because the turbo engine from Ferrari was not good, we were fighting to be in Q3, and McLaren-Honda had one year of development for free. They were not racing in 2014 and that was a mega decision. So I was hearing that and so 9 of 10 were going into the direction.

"I don't regret many things, I'm happy with the decisions."
