Liverpool manager Jurgen Klopp says hard work is the reason why the Reds registered a very important away win against Sunderland.
The Reds will face West Ham United today in what could be a very tricky game for Klopp's men.
But the German says his players are ready for what could be a difficult game at the Boleyn Ground.
"It's always a test and we always have to be prepared to get good grades in the tests we have. We need points, that's clear," Klopp said.
"But first of all, you have to fight for the result and that's the biggest change in the last two games.
"Until then, we won our really good games where we were really good but we were average when we lost. That's not how it should be if you want consistent results.
"We took these points, very important points, in a very difficult game. That's very important. We defended well and we had opportunities.
"You can always make your life easier in games like [Sunderland] when you take one of your first opportunities. I think the biggest opportunity for us came when Phil [Coutinho] played a pass to Roberto [Firmino] in the box and he couldn't save the ball.
"It was one touch and the second touch was with the knee. If he could control this ball it was a big, big chance and you can make an early goal in this game.
"For us it could make life easier but if you don't do this you have to work, defend and to switch [the play], speed up, slow down - all the things for the special moment [when you score].
"So it's very important in games like this that you win. It's important for us that we don't wait for the perfect day but that we work for the perfect day.
"If you always are prepared for a difficult game, sometimes you will find an easy game. But if you are always waiting for the easy game, you will never find it.
"That's an old football rule and yesterday we worked again for it and for us it's very important."
