“If you really have physical problems, you will not win. If you have some pain and it’s not putting you in a situation that limits you, the movements, maybe you can find a way.
“But when you really, really have an injury, it’s impossible to win a tournament like this.”
Speaking on Sunday, Djokovic admitted he may have to take some time off after the Australian Open to get over the injury.
He said: “It will jeopardise, you know, depending on how I go here, it will jeopardise certain tournaments that are coming after the Australian Open that I was maybe thinking to play.
“So I’ll probably have to, you know, take a little bit more time than I was previously thinking and heal, recover, and then get back on the tour.”
