Speaking after announcing his decision to step down at the end of the season, he joked: “The last three years, you can count as dog years.

“If you look at a picture from 2015 and now you’d say: ‘That’s only nine years (apart)?!”

Klopp has had both his teeth and eyes done during his Anfield tenure.

His transformation has seen him ditch his glasses and amaze fans with his pearly whites.

The 56-year-old has reportedly had veneers implanted during his time in England.

Dr Robbie Hughes, who has become the go-to dentist for Liverpool players, said in 2019: “Working with Jurgen Klopp came about because he saw Roberto’s new teeth and decided he wanted to do something.

“When Jurgen came to see us, he basically just said he liked Roberto’s teeth, that he wouldn’t want to go quite as white, but he liked his teeth.”

However, Klopp later claimed he had instead had them fixed after an initial medical problem left him needing antibiotics.

He explained: “It was not that I saw Bobby Firmino’s teeth and went ‘I want them!’

“It’s a long procedure and I had to go to the toilet. When I went I looked in the mirror and they’re really small – I realised, that’s the point of never going back, you have to do it now.

“I mean I like them, but obviously it’s different. They feel comfortable, it’s all good.”

As for his glasses, Klopp ditched them after his first six years in charge, having worn them since the age of ten.

The Reds boss underwent minor surgery to fix his eyesight during the summer of 2021.

He told Bild at the time: “It’s actually totally private, but I can explain it to you once, too. I’ve been wearing glasses since I was ten years old – that’s 44 years.

“The problem in recent years was that the glasses could no longer correct my poor eyesight.

“The solution to this was a minor intervention. It wasn’t lasering or anything, but it made me see very well without glasses at the moment.

“I think my face is weird without glasses, but I don’t need them anymore.

“I may need one more. When that happens, I’ll wear glasses again.”
