Jurgen Klopp said any bad blood with Sam Allardyce was in the past as he welcomed the appointment of the new Everton manager.
Klopp and Allardyce clashed verbally when the latter was manager of Sunderland two seasons ago.
Allardyce branded Klopp a "soft German" after the Liverpool boss was so incensed by a tackle from Jeremain Lens on Mamadou Sakho that police stepped in to calm the tension between the two benches.
Allardyce then apologised after claiming Liverpool's injury problems were down to Klopp's style of play.
The pair do not have long to wait for their next encounter, with the first Merseyside derby of the season taking place at Anfield on December 10.
Klopp said: "With Sam I have kind of a history, when he was at Sunderland and he said something after the game.
"Then he was the manager of the England national team and we had a very good relationship.
"I'm happy for him, it's good for us when Everton is in a good moment."
