Fernando Alonso says he could make Formula 1 return in "three years"

After winning in Sebring, Fernando Alonso has made it clear he will not be focusing on Formula 1 this year, but he will not rule out anything by 2020.

The Spaniard won the 1000 miles of Sebring last week with team-mates Sebastien Buemi and Kazuki Nakajima and announced shortly after the race that the single-seaters are doing little to him at the moment.

"I haven't really followed Formula 1 in recent days. I don't know and to be honest, it doesn't really matter to me," Alonso told the Spanish branch of Motorsport.com.

The 37-year-old is still keeping the Formula 1 return door open for a little while to come, however.

"I have not ruled out anything before 2020. When I announced my departure at the end of 2018, it was because I wanted to take on other challenges. I don't have a crystal ball to see what I will do in the future," he added.
