Fernando Alonso isn't ruling out a return to Formula 1 in the future, insisting he is fit and young enough to still be competitive in a few years.
The two-time champion recently announced his retirement from F1, with his focus now on securing motorsport's unofficial 'Triple Crown' of winning the Monaco Grand Prix, Le Mans and the Indy 500 – only the latter of which he has yet to win after an unsuccessful attempt in 2017 when his engine failed.
Although Alonso hasn't announced his 2019-plans, which will include the second half of WEC's 'Super Season', it's believed he is close to agreeing a deal to race in IndyCar full-time.

But the Spaniard hinted that he wasn't completely done with F1 and a future return could be on the cards.
"I think the door is open [to an F1 return] because I think I am driving at the best level of my career now," he said on Friday in the build-up to the 6 Hours of Silverstone. "Why close doors…anything could happen in the future?
“I am still young. I am not 45 years old. I feel strong and I am doing this year 27 races."
Alonso also expanded on his reason to quit at the end of the current season, citing a lack of on-track action as the main reason.
"The action on track is not the one I dreamed of when I joined F1, or when I was in different series, or the action on track that I experienced in other years," he said.
"I stopped because the action on track in my opinion I feel is very poor. In fact, what we talk about more in F1, is off track. We talk about polemics. We talk about radio messages. We talk about all these things, and when we talk so many times about those things, it is a bad sign."
