Liverpool boss Jurgen Klopp admits some of his players weren't at their best for the 1-1 draw at West Ham.
Sadio Mane's opener for the Reds was cancelled out by Michail Antonio.
Klopp said, "Not our best of course. it was difficult because of the opponent and our own situation.
"We had good moments.
"We score the goal which was offside
"The referee must know that at half-time, it explains the second half because I think the referee knew and you saw there were a lot of strange situations, not decisive, just rhythm breakers."
Speaking to the referee after the game: "I was really calm. He said we don't talk at all.
"There were so many situations where it was 50-50 or 60-40... free kick for the other team. As a human being I know if I make a big mistake in the first half I don't want to open the gap even more.
"They scored the goal and it was a deserved draw.
"I didn't see a good game from us, a couple didn't perform at the highest level but that has happened before and it will happen in the future."
