With Liverpool returning to the top of the Premier League over the weekend, a former Reds star believes Jurgen Klopp's side have no weaknesses.
Goals from Georginio Wijnaldum and James Milner guided the Reds to a 2-0 victory over relegation-threatened Cardiff City.
The Merseyside outfit now sit two points clear of Manchester City and Greame Souness feels it will be tough for opponents to expose Klopp's side.
"If you're going to be champions you've got to deal with the challenges that come along in many different ways," Souness told Sky Sports.
"I think today they looked like a composed, polished team. They were patient, they didn't try and force it. It wasn't a great pitch to play on, playing under a lot of pressure and I thought they were fabulous.
"OK, they weren't at their slick passing best but they were still a fabulous team today and I think they showed a maturity as well - 'we believe in what we're doing, we're not going to rush this and eventually someone will come up with something for us' - and that is how it panned out.
"They were very polished today.
"It was only a matter of time. When you're that good as a team and you've got that many special players, the threat's not coming from just one area. It could be a set piece with [Virgil] van Dijk, it could be a piece of magic from one of the front three.
"But the threat comes from so many places that they know, 'keep a clean sheet, keep doing the things that have got us the results over the last nine months and it will come' and that's how they played today.
"They should be, they are a team without a weakness. If you're setting up against them, where do you think you can expose them? I think you're struggling to come up with any weaknesses in their team."
