After leading Liverpool to Champions League success last season, reports were that, the German trainer was near a contract renewal at Anfield.
But the former Borussia Dortmund tactician believes it is too early for contract talks with Liverpool.
"I will not leave before the contract is ending. That is my side. That is why a contract is important.
"We have enough time to make decisions in that department. There is no need to do it now. Three years is really a bit early to be concerned. It is just a contract.
"The owners like what I do. I like what the owners are doing. I love the team, they are brilliant. Melwood is sensational. I'm looking forward to going to [the new training ground in] Kirkby and all these things. There is always a step forward.
"We all want to keep the past and traditions and all that stuff, but there needs to be a step forward. It is important that is our attitude. You cannot make that step in three or four years by making sure that I stay until 2000-and-something. It just makes sure that I will stay until then."
Liverpool will begin their 2019/20 Premier League campaign with a game against newly-promoted side Norwich City on August 9.
