Jürgen Klopp's first taste of the famous Liverpool-Manchester United rivalry ended in disappointment with his team falling 1-0. After the match, the manager expressed his disappointment in not capitalizing on opportunities.
"I feel really bad," Klopp said at his post-match press conference (via Sky Sports). "It's a derby and in a derby you only have one job to do and that is to win to have any chance of being satisfied after the game.
"The performance and a lot of things we did today were really good. Creating chances was good, finishing was not, otherwise we would have scored a goal."
Meanwhile, Klopp lamented and explained the string of errors that led to Wayne Rooney's 78th minute goal, which granted United the narrow victory.
"Set-play (Rooney's goal) was unlucky because we changed some players before - I had to change two positions for defending set plays," he said. "We didn't prevent the cross, we lost (Marouane) Fellaini and lost Rooney. They got the goal and there was not enough time to get back into the game.
"So at this moment, it is only frustration, but we have to carry on, and we will."
