Liverpool goalkeeper Alisson Becker says they're becoming "too easy" to play against.

Defeat at Manchester United ensured they continue to suffer their worst start to a top-flight campaign in a decade having already fallen seven points off the lead after just three games.

And Alisson believes opposing teams are finding it too easy to capitalise on the weaknesses in Liverpool's much-scrutinised and unique approach.

“Teams, when they play against us, they know the way we play and they try to exploit that and they try to use that against us," said the goalkeeper. "(It's) something that most times works for us, (but) sometimes we get punished for that and tonight it is what happened.

“Sometimes we have to be more perfect in a game. It's difficult to do that, but as a team being together we can do that and we can improve. We just have to keep working hard in our game in everything and defending with the ball.

“How do we change it? With our attitude changing that. Sometimes during the games we make a few mistakes that you get punished for that."
