Can has been absent for the last three games after being forced off in last month’s 5-0 win over Watford, as well as withdrawing from international duty.
“We’re still hoping it will be a little bit quicker than maybe we thought in the first moment,” he told LiverpoolFC.com, “but we cannot say anything else.”
Unfortunately, speaking to Sky Sport Germany in the buildup to the Reds’ trip to the Etihad, Klopp has elaborated further.
Asked whether Can’s campaign was over, the manager simply replied: “Yes.”
Quite why Klopp opted to provide more clarity in one interview than another is unclear, but there could be no more definitive statement than the one provided in his native tongue.
If the 24-year-old is sidelined for the rest of the season, there is a strong likelihood he has also played his last game for Liverpool.
Can has just under three months left on his current contract, and is yet to show any willingness to extend his deal at Anfield.
This would prove a disappointing end to what has been a promising career with the Reds, with the No. 23 making 166 appearances since joining from Bayer Leverkusen in a £10 million deal in 2014.
He is clearly a hugely important player, both for now and for the future, and that there is still slim hope he could re-sign with Liverpool is at least encouraging.
