Jordan Henderson could make his Liverpool return before the end of this season.
Henderson has not featured for the Reds since their over Tottenham in mid-February due to an ongoing foot injury picked up during training that month.
The midfielder continues to be plagued by feet-related problems. He was sidelined for a sizeable part of last season with plantar fasciitis, a heel condition.
But Klopp is refusing to rule out Henderson’s participation in Liverpool’s final two games of the campaign, against West Ham and Middlesbrough respectively.
He said: “It is too early to say [his season is over].
“Next season is the latest moment, of course, but anything can happen. We stay positive because he is strong.
“The moment someone gives him the green light he will be back in a second because of his attitude and character.
“I am not thinking about the start of pre-season but that would be the latest moment he is back.
“You wish a ligament had snapped. Then at least you know if you can fix it or if you have to wait for six, eight weeks or whatever.
“This is the kind of issue where you have to wait. That is how the body is sometimes. Jordan can manage really well. It was the medical department that said he has to rest.
“We still have to wait, that is all.”
