The Liverpool captain is in the running for the prestigious accolade alongside Stuart Broad, Hollie Doyle, Tyson Fury, Lewis Hamilton and Ronnie O’Sullivan.
Fans can vote for Henderson either online or via phone – and Klopp will be doing just that himself.
He said: “He would have my vote. He’s an exceptional person, exceptional player.
“He did a great job in the summer, for our players but for players in general, he’s doing that for the England national team, he’s involved in pretty much everything.
“He is a great guy and would be a worthy award-winner, but I don’t know exactly who are the other people. It’s all about that. But he would be a worthy winner.”
