Jurgen Klopp had to choose between Cristiano Ronaldo and Lionel Messi for the only selfie on his phone

Liverpool boss Jurgen Klopp had to choose between Cristiano Ronaldo and Lionel Messi for the only selfie on his mobile phone.

The German has come up against both titans of world football in his managerial career and has spent time in the same vicinity at awards ceremonies.

Klopp isn't massively into taking photos yet it was at one of these events where he felt the need to make one special exception.

The 56-year-old took a picture with eight-time Ballon d'Or winner Messi even though Ronaldo was also floating about.

"I have one selfie on my smartphone," Klopp said said during a special Q&A at the LFC Foundation Gala dinner premiere in 2018. "That's with Messi. Cristiano was in the room, as well..."

You can't blame Klopp for whipping out his smartphone and taking the priceless picture.

He later talked about the snap in an interview with Sky Sports, where he discussed his fandom of Messi.

He said: "I have just one selfie on my phone with ‘strangers‘ I don‘t know personally: It‘s with Messi. I am a fan, I like a lot of footballers... If you love football, how can you not be a fan of Messi? That‘s impossible."

Klopp saw Messi's brilliance up close and personal in 2019 when he scored an outrageous free-kick for Barcelona against his Liverpool side.

Liverpool went on to complete a miraculous second leg comeback at Anfield to reach the final.

A year on and Klopp made his pick in the Messi and Ronaldo debate, praising both for their incredible achievements.

"For me Messi, but I couldn't admire Ronaldo more than I do already," he told YouTube channel freekickerz when asked the burning question.

"The explanation is the following: we've played against both already and both are almost impossible to defend. But Messi has much lower physical requirements from birth on.

"If you could paint yourself a perfect player, it would have Ronaldo's height, he could jump and run as high or quick as Ronaldo can do. And what is then even added to that is his total attitude, it is absolutely perfect and professional, it couldn't be any better."
