Tsimikas completed his switch to Liverpool from Olympiacos last week and has linked up with his new teammates at their pre-season training camp in Austria.
Looking ahead to 2020-21, Klopp explained how the Greece international's presence can help the squad successfully navigate certain challenges that await.
"Kostas is a signing which just shows what we are looking for, what we need," the Reds boss told Liverpoolfc.com from the team hotel. "I think the left-back position was now not a position where the people out there would have thought, 'We need another player' and stuff like this.
"It worked out pretty well, Millie played there from time to time but we cannot take any risk or we should take as less risk as possible.
