The two tennis icons will work together at the upcoming Australian Open and Henman thinks it could provide the Serb with a fresh perspective following a disappointing 2024, even though the development came as a surprise.
The former player told Eurosport: "Andy's decision to coach Djokovic certainly took me by surprise. When I saw it on the internet, I had to check the date, whether it was an April Fools [joke].
"But no, I think it's a smart move from Djokovic, because Andy's played against all those opponents that Djokovic is going to be up against. Andy's always been a great tactician, so I'm sure that fresh input can motivate Djokovic.
"And from Andy's point of view, having just retired in August, I was surprised that he wants to get back on the road that quickly. But only time will tell how the relationship evolves."
Murray only retired from the sport this summer but Henman thinks that the former world number one has made an instant return because the chance to work with Djokovic is "too good an opportunity to turn down".
The pundit said: "At the end of the day, Andy's the one that's got to answer that question, what was the motivation?
"But I always felt that he would go into coaching. I didn't think it would be this quick, but when you get the opportunity to work with one of the greatest players in the history of our sport, then perhaps he viewed it as too good an opportunity to turn down.
"It just adds another great storyline around the Australian Open in 2025."
