Former heavyweight world champion George Foreman gave praise to newly elected President, Donald Trump, during a recent appearance on “Fox & Friends.”

Foreman compared Trump's battles with the many opposition groups to the numerous boxing matches he participated in over the years.

He advised Trump not to listen to his detractors and stay on message, saying that while "in the ring" he would not listen to the "boos" from the crowd until he was home watching the match on tape.

“You know, when you’re into something like this, you just gotta fight,” Foreman said.  “You can’t even worry about the audience,” Foreman told hosts Steve Doocy, Ainsley Earhardt and Brian Kilmeade, when asked about how Trump “not [taking] a backwards step” changes the view of the president’s opponents.

“When I’m in those boxing matches, I hear, ‘Boo, boo, boo,’ after the fight, when I listen to them on the tape. But in the ring, you don’t listen to anything. You must step forward and fight,” said Foreman.

Foreman, who said over the years that Trump “would always take my calls,” also weighed in on why the real estate mogul won last year’s race for the White House. It was a big shock to many when Trump defeated heavily favored Hillary Clinton in the Presidential race.

“Sometimes people win just because they’re winners,” Foreman said. “Some people lose just because they never thought they really would win, and they lose. Winning is an idea, once you get in it, you can’t lose.”
