Liverpool manager Jurgen Klopp has admitted that his squad may be lacking the quality they need to be consistent in the Premier League.
The Reds claimed a 3-1 win over Arsenal on Saturday, which means they remain unbeaten against the current top six teams in England's top-flight.
However, Klopp's charges have tasted defeat against Burnley, Bournemouth, Swansea, Hull, and Leicester, and the German tactician has conceded that it may be due to a shortage of quality.
"I don't want to make it too philosophical," he told the press. "It is obviously the case we are inconsistent. I know we don't have to doubt the attitude, and the kind of attitude we usually are looking for was here against Arsenal – they were really motivated and you cannot play like this if you have any issues – but we struggled in other games.
"So, OK, you say it is about quality and sometimes probably, yeah, we don't have the quality, but with quality you have potential, and you make quality with work and all that stuff.
"If we judge the players after the best game of the season, then we sign a contract for another six seasons; if we do it after Leicester then you change the whole squad. But the truth is always in between. That is what we are working on, really working on.
"There will be moments when we play like this [against Arsenal] and win again — and it is what we did this season already, in fact – and it will be against a team not in the top six, but we have to work on it. First of all, we have to feel like it is possible."
