I think Klopp is leaving at the end of his contract, which is about 2 more years I think?
Their squad is at their current level is mostly Klopp's credit. They have a tendency to go for bargain bin hunts, only Klopp managed to turn the mediocre signings into world class wonders. Rodgers couldn't do it, Dalglish couldn't do it, Hodgson couldn't do it. Even the fans wanted Henderson out before Klopp arrived. Without Klopp, they will probably be back where they were before he arrived - mid table.
That is of course, they find another Klopp.
