And what better way to celebrate with the Liverpool manager, than by wishing the German well on his special day.
But one fan took it too far.
Cake artist Ben Cullen has created this Elvis Presley / Klopp look-alike.
The 26-year-old said: “I made the cake because I am surrounded by Liverpool fans within my circle of friends and my family, and I like what I have seen of Jürgen.
"He is a great character and has quickly become an iconic and recognisable figure within the sporting world."
