Manchester City's loss to Newcastle the night before presented Liverpool with a great chance to extend their lead, but an unbalanced team and icy conditions made for a hard evening against the resilient Foxes.
Sadio Mane handed the home side an early lead within 3 minutes of kickoff as he perfectly found the bottom corner from his effort.
In yesterday's other game, Wilfried Zaha scored and was later sent off for Crystal Palace in a 1-1 draw at Southampton.
"The 1-1 is OK even though everybody agrees it should have been a penalty", said Klopp.
"There was not enough man power to clear all the pitch".
With just 5 points seperating them at the top of the table, it's likely that one of Manchester City or Liverpool will hoist the Premier League trophy this year, with the latter being the most likely at this point.
City defender Kyle Walker took particular delight in Liverpool's draw, mocking the result on Twitter before deleting it. I think for Liverpool having fewer competitions gives them a better opportunity of winning the league.
"But it is nothing to criticise because I don't understand so how can I criticise it".
You'd experience less ups and downs during a weekend at Alton Towers than supporting the Reds over the next three-and-a-half months, and if Anfield on Wednesday night was anything to go by it'll have sucked the living soul out of most of us before the race is run.
"I never celebrated that another team dropped points or lost a game", the German told reporters.
I wouldn't be surprised if we saw goals in this game and was toying with the idea of a Watford over 2.5 goals double but, at a shade over 2/1, I'll play safer and go straight on the Hornets win. The first half we had 80% of the ball so only one team suffered and it was us. We wanted to win a football game, we didn't win it and so we don't feel brilliant. I do think they're in for a test, however, and backing an away win including a goal for the home side at almost 3/1 looks worth a go. "It was another hard start to the game".
The Reds return to Premier League action with a hard trip to West Ham United on Monday night.
"I'm not sure what that says about us, but it says something about them", the Liverpool boss said.
