The 49-year-old has come under fire this season, with his side struggling both at home and in Europe.
But Benitez has hit back at his critics - and reckons the Reds' health is as rude as ever.
He told The Sun: "There is a massive difference between five years ago and now.
"The name of the club round the world is at the same level as it was in the 1980s.
"It's a fantastic achievement. Everybody talks about Liverpool in a good way. And we will get better."
