“At this moment, I think Mane and Salah are going through poor form. It happens,” he told Sky Sports last month.
“I’m still confident that Mane and Salah will start scoring goals again, but I must say I am worried for Firmino.
“Last season, when he wasn’t getting the goals and assists, you’d say, ‘well, look at what else he’s doing from the front’.
“He’s the one I’m worried about, whether it be a lack of form or maybe just that slow decline as you get a little bit older, which is natural for any attacker when they get to their late 20s because they don’t play as long as players in other areas of the pitch.”
Klopp already has eyes on his next three years in Merseyside, assessing his options without Firmino, could be a vital part of those plans.
