Liverpool boss Jurgen Klopp says Arsenal deserved their victory on Sunday.
The Reds lost 3-1, with Ibrahima Konate being sent off for two yellow cards.
Klopp later said: "In general we can admit that Arsenal deserve the three points.
"The circumstances were a bit strange. The goal for us was similar to the cup game. In the cup game we had even bigger chances.
"We scored the goal at half-time and having nil shots on target, but a goal is a bit stranger. We had to adapt in a lot of moments today.
"We found our way into the game, we had crosses and situations where it was close and then the second half. But if you cannot keep it open, then Arsenal might become a little nervous.
"The red card did not help and we had to change what we tried a lot.
"If this game ends 1-1 then what do we think then?
"Because of the way we conceded the second goal and if we stayed in the game with the changes we could have changed the game into our direction.
"We gave them all the momentum.
"We didn't miss players more than before as we always miss them.
"We had possession and just didn't have the finishes, we found Trent on the wing and the ball flew in and Arsenal were under pressure.
"But I thought in the first half we went step-by-step to get in the game."
On Konate, he added: "A lot of things were against of us today. This referee gave me a red card against Man City for wrestling situation between Bernardo Silva and Mo Salah. Today same situation with Jota but didn't get a red card.
"It is unbelievable, then the of holding Havertz on Konate for the first yellow card.
"Then Havertz goes down and the referee gives Konate a yellow card.
"Gabriel does the same to Nunez and no yellow card."
