Fernando Alonso releases YouTube video after crash: 'I'm completely fine'

McLaren's Fernando Alonso has told fans that he is well after crashing heavily in testing last weekend - but no decision has been taken on whether the Spaniard will compete in the 2015 Formula One season-opener in Australia.

Alonso, who crashed his McLaren in pre-season testing at the Circuit de Catalunya, spent three nights under observation in hospital in Barcelona before being released on Wednesday to recover fully at home.

The 33-year-old spoke publicly for the first time since the accident in a video message posted on YouTube, saying: "As you can see, I am completely fine."

"I would like to be at the test this week in Barcelona but the doctors' recommendations are to wait a little bit, a couple of days.

"I will rest this weekend and keep you updated next week with progress."
