Apparently the pitch at Anfield is terrible:
Liverpool boss Brendan Rodgers, speaking to BBC Sport: "There's no doubt we deserved to win the game, our performance level was outstanding. Our performance today was better then when we won here last year 5-1. We had total domination of the first half, and 1-0 was probably about right. But then we gave away a disappointing goal right on half-time, and that can leave you a bit deflated.
"In the second half we continued to press, probe and create, and then all of a sudden we gave away a poor goal. There's no problem with our organisation. It is the decision making that can be our problem, and you cannot make poor decisions if you are going to keep clean sheets. But even down to 10 men we kept penetrating and the goal at the end was the very least we deserved, for the character we showed."
"It was an outstanding performance, our passing and movement on the pitch, which is terrible, was superb.
"We deserved to be one up at half-time and I don't think it was a free-kick in the build-up to their second. Alexis Sanchez dived for me and the referee bought it, but we have to defend better. We lost three duels and we need to win the first one.
"I'm delighted with our performances this week against Manchester United, Bournemouth and Arsenal, it shows we are getting back to where we are.
"At half-time we asked for more of the same with the same movement and then we showed great character to fight back from 2-1 down with 10 men.
"I don't think before this week we have been close to that level of speed and thought. You have to be creative as a coach to find a system that brings you back to that."
