Premier League fans couldn't believe their eyes as a legend of the top flight shared a photo of his teenage self.
The German was congratulating compatriot Boris Becker on the 40th anniversary of becoming the youngest player ever to win Wimbledon.
Former Liverpool boss Jurgen Klopp took to Instagram on Monday morning to post a photo of 17-year-old Becker with his trophy on Centre Court in 1985.
The 58-year-old shared it alongside one of himself enjoying a drink at the same age.
'@borisbeckerofficial vs me at 17… aged like a fine wine,' he wrote under the images.
