Other than the Farce India saga, it's been a frustrating day at Spa-Francorchamps, what with Lance Stroll suggesting that moving to his father's team is the very last thing on his mind and then Fernando Alonso claiming that he is walking away from F1 for good at season end, only to add an infuriating "but you never know" moments later.

"Right now, I am thinking that it's a goodbye," the Spaniard told reporters. "But, you know, life changes very quickly. And life also taught me in the past how things may change, in a couple of months' time, or years' time.

"As I said in the press release when we announced my retirement, it is to leave the door open, because I don't have a crystal ball to know what is going to happen in the future," he added. "So as I said, for me it is bye-bye, but who knows what will happen in the future?

"It was a decision that probably I started thinking about last year," he continued, "and then this year, 2018, there were a lot of changes in the team so I thought that it was worth staying one more year.

"I enjoy driving these cars with these regulations, the big tyres. I was having fun. But a couple of months ago I decided that it was the right time. I feel strong, I feel driving at a good level and I want to say bye-bye to this sport when I feel strong, not when I feel not competitive, or I don't have any place to go or whatever, and you say bye-bye. I prefer to take my own decision and find new challenge that maybe F1 cannot offer me at the moment."

Asked about his plans for the future, he replied: "I think the challenges are probably bigger than the challenges that I can find here for next year.

"The triple crown is something I have been saying for a couple of months now, or years... that to be best driver in the world, there are two possibilities, winning eight world championships in F1, which is unlikely now for me, or second is to master different series and different cars.

"In Sportscars I think I'm doing quite OK at the moment, so I'm happy with the performance I'm seeing there. The Indy 500 I felt competitive last year, and there are other series that can put you in a different level in motorsport, if you can win with different cars, in different series.

"The possibilities for next year, they've been a few, or a lot, depends what you look at it," he said, referring to F1. "I did not say because as I said also last week because there are probably only two teams which can win and they continue with their drivers for the following years.

"The F1 we're seeing now was maybe not the F1 I dreamed of as a kid or when I joined in 2001. That's a bigger reason. I think definitely it plays a part of it, if you are in one of those two teams you probably keep going even if you don't enjoy the races or trips or amount of years you have been doing the same thing."
