Matip has missed the last three games with an adductor injury suffered during the 1-1 draw with West Brom, with Klopp forced into another change to his back line.
The Cameroonian was not present in training in the buildup to Sunday’s clash with Man United, but there is still time to report back to preparations and prove his fitness for a starting place.
Given how reluctant Klopp has been to rush his players – and Matip in particular – back so far this season, it seems unlikely he will start against the Premier League leaders, but speaking in his pre-match press conference, the manager said “it’s not decided yet.”
“Joel is close,” he told reporters.
“Does it make sense now to throw him into a game with one or two sessions – which he didn’t do yet, but today and tomorrow he might be involved – and bring him in?
“I don’t know, we have to see. We have to decide it then. We have to look at him, how he trains and how he looks in training, these kinds of things.”
However, in his explanation, he suggested Henderson would return to midfield if possible, which would be the case if Matip was fit.
Klopp concluded: “We still have different solutions, and Hendo is for us very important in midfield as well, so we just have to see. But it’s not decided yet, why should I?”
