A draw was enough to send United to the Premier League summit, for a few hours at least, while stretching Klopp's impressive record in meetings with fellow "big six" sides.
"I needed my bench, and I didn't have a bench", he said.
Jurgen Klopp's style isn't exactly conducive to favouring not losing over winning, though, and the German is highly unlikely to change his philosophy for United's visit this weekend, despite his side going seven matches without a clean sheet across all competitions and only West Ham United and Crystal Palace having conceded more Premier League goals this season.
"It's quite hard when a top-class team like Man United has that defensive approach".
"Manchester United came here for a point and got it", Klopp said. The Manchester United manager won three with Chelsea, so he certainly does not need to be told that some points are better than others and that a title can not be won by playing champagne football every week.
"When we play at home and we don't see big enthusiasm in the people, we complain". I am okay with the performance - it is not my job to judge the United performance.
"They were great games to play in and I expect tomorrow to be no different".
The United boss, who did not start Marcus Rashford as a result of a knock, defended his team's tactics and said United came to win the match. I waited for Jurgen to make a change, go more attacking, but he kept with the three strong central midfielders.
"When I brought on Jesse Lingard and Rashford I was waiting for him to bring on Daniel Sturridge or Dominic Solanke". "That midfield was stronger than my midfield".
"That midfield today was stronger than my midfielder".
While it is still too early to come to any final conclusions regarding the league table, a 10-point deficit would be a very big ask for Liverpool to overhaul considering how impressive both Manchester City and United have looked thus far.
Klopp felt his side dominated the game and felt his side should have had a penalty after Philippe Coutinho went down under pressure from Ander Herrera. It's hard, the motivation was at a high level for them and for us.
At the end of the season, this point may be the one that wins United the title, but the two points they could have picked up may ultimately be the difference between finishing first and finishing second.
As for those watching from the stands or on TV, Mourinho described the second half as "a game of chess".
