Liverpool boss Jurgen Klopp is wary of facing Paul Clement's Swansea City today.
Klopp has praised Swansea's "unbelievable improvement" since new head coach Clement took over at the Liberty helm.
Klopp said: "I'm not sure I have ever seen such an improvement in such a short time, the playing style, what they have done is a really unbelievable job."
The former Borussia Dortmund boss also credited Clement with returning Swansea to their traditional style of attractive football.
"Before they were a football playing side and that's what they're doing now. We don't only watch results, we watch performances so we knew about their quality."
