Newcastle United boss Eddie Howe admits he doesn't get along with Liverpool rival Jurgen Klopp.
However, ahead of Sunday's clash, Howe says he's not seeking to make any friends in the Premier League.
Asked about his relationship with Klopp on Friday, he said: "I don't really have a relationship with any manager, I'm competing against them.
"I find it very difficult to have personal relationships with competitors. I've been the same as a player. I was not one to talk to players before a game. I draw a line, and so that is just how I have always been.
"I respect Jurgen a lot. I think he's done an incredible job. He's an unbelievable football manager but I draw the line at friendships because they don't exist for me."
He added: "When you grow up in a house of three brothers and a sister, I think naturally you just compete for everything. You are fighting for attention I suppose. You are fighting for anything. Then, you start to play little games which I would create, games with my brothers which I would want to win, so maybe it's gone from there.
"There's no such thing as a friendly, even now with my kids, I've got to try and win. That is built in me somehow."
