Aliens are more likely to land in London than Leicester City winning a second consecutive Premier League title, according to Claudio Ranieri.
The Foxes overcame 5,000-1 odds to memorably win the title last season as the traditional big teams all faltered.
However, the 64-year-old expects Manchester United, Chelsea and Manchester City to mount strong challenges after Leicester finished 10 points clear in 2015-16.
"It's easier for ET to come to Piccadilly Circus," the Italian manager told reporters at a press conference.
"It is impossible. It is more difficult than last season. It is normal that we can't win the league. For this reason I say the bookmakers must do 6,000-1.
"I am very curious, all the world is curious, what will happen with Leicester. I am very curious to see where we finish."
Leicester will kick the new Premier League season off away to newly-promoted Hull City on Saturday.
