Liverpool boss Jurgen Klopp admits "attitude" is crucial in any new signing he plans to add to his champions-elect squad.

Timo Werner has become the latest player to express his admiration for the European and world champions with the RB Leipzig striker suggesting he would be a good fit at Anfield.

But Klopp warned: "Usually if people mention 'the best team in the world,' you think of Real Madrid from a few years ago, Barcelona from a few years ago, Man City of the last two years and stuff like this.

“The team we have is about attitude – go and go and go – mixed with really good football players.

“We are for sure more critical of our performances because they (people) only see the results, which are exceptional – no doubt about that – but we don't see ourselves as the best in the world.

“On the one side, it's easier if players see you as that. If they see you are successful, it's easier to get into talks with players.

“But on the other side, it's more difficult the better your team is because they ask questions like 'where and when would I play?'

“We need players who want to be part of this, who want to fight for their spot, who want to make the next step together with us, who want to develop and improve so that's it.

“We have these players and whoever wants to join us, needs to have exactly this kind of attitude."
