Klopp reflects on Liverpool's 1-1 draw away at West Ham, which sees them go three points clear of Man City.
Jurgen Klopp thinks Liverpool couldn't get a win at the London stadium because of refereeing decisions.
Liverpool had the chance to re-establish their five-point lead over Manchester City [who beat Arsenal 3-1 on Sunday with Sergio Aguero scoring a hat-trick to narrow the gap to two points] when they took on West Ham on Monday night but eventually played out a 1-1 draw with the east London club.
The Reds broke the deadlock through Sadio Mane after the Senegalese slotted home with a cool finish from seven yards in the 22nd minute, but the Hammers responded six minutes later as Michail Antonio finished off Felipe Anderson’s assist.
It was a thrilling encounter as both sides created chances but weren’t able to score more, with the Hammers creating a wall Klopp’s Reds couldn’t breakdown.
And following the match, Klopp told Sky Sports: "We had good moments, coming through the channels and scored the goal, which I've now been told is offside. This explains a little bit the second half, because I think the referee knew at half-time.
"He knew it for sure at half-time, and then you saw a lot of strange situations. They were not decisive but just rhythm breakers. That obviously didn't help us.
"If I've made a mistake in the first half, I don't want to open the gap even more as a human being."
The Merseyside club have dropped seven points in their last five games, losing to Manchester City before back-to-back draws with Leicester and now West Ham and Klopp confirmed they weren't at their best on the night.
The German added: "It was not our best performance of course because we came up against difficult opponents.
"It's a deserved draw which we'll take now. We'll see who's available for the weekend and we'll move on.
"We had to play in a different formation because we had to change three times after training, which doesn't help with the rhythm.
"We dealt with their quality apart from at set pieces. We had to change three positions and obviously that makes things harder. They are really strong in that department.
"We have to accept that [the pressure]. We have to perform better. That's all I'm interested in and concerned about.
"A couple of players didn't play at the highest level tonight, but it's happened before and it'll happen again. We will deal with that."
