Fernando Alonso has hinted again that his future lies at Le Mans.

The Spaniard, who has never hidden his passion for the ever-burgeoning world endurance championship and the 24-hour race, has said that if F1 does not get a lot racier in 2017, he will not renew his McLaren contract.

Now, as he paid tribute to his friend Mark Webber at the Australian's final WEC race in Bahrain, Webber hinted that his future definitely lies at Le Mans.

"You didn't wait for me - it would have been nice - but I think you will be around so I will ask you many things when I join your adventure," Alonso said in the video tribute to Webber that was played on the Bahrain big screens.

Another potential Le Mans contender of the future is Jenson Button, but the Briton says he will not be heading to the race during his sabbatical next year.

"Nothing is set in stone, but I am sure Honda would not want me racing for a main competitor, which is completely understandable," said Alonso's current McLaren teammate.

"I won't be racing at Le Mans next year because the right opportunity isn't there, but hopefully it will be in the future."

Alonso and Button are 10th and 15th respectively in the drivers' standings ahead of this week's season-ending Abu Dhabi Grand Prix.
