US president Donald Trump discussed Cristiano Ronaldo with his Portuguese colleague Portuguese President Marcelo Rebelo de Sousa, as reported by CNN.

Ronaldo has had an impressive World Cup, scoring four goals in three games and helping Portugal qualify for a last-16 clash with Uruguay on Saturday at Russia 2018.

"So, tell me, how good a player is he?" asked Trump. "Are you impressed?"

"I'm very much impressed. He's the best player [in] the world," enthused Rebelo de Sousa, adding he believes the World Cup has been "a success for the world."

"So will Christian [sic] ever run for president against you?" Trump asked De Sousa. "He wouldn't win! You know he won't win?"

The Portuguese politician paused for thought, before grabbing Trump's arm. "Well, President, you know [there's] something I must tell you: Portugal is not the United States. It's a little different!"

To be honest, I wouldn't bet on that. Cristiano Ronaldo would win presidency. And not only in Portugal, but most countries of the world. Not sure about the US though.
