Carlos Carvalhal insists Swansea can upset Liverpool in a contest he has labelled "David versus Goliath".
Free-scoring Liverpool are unbeaten in 18 games and head to bottom club Swansea fresh from ending the unbeaten record of Premier League leaders Manchester City.
But Carvalhal says he has identified weaknesses in Jurgen Klopp's side after studying the footage of that 4-3 Anfield victory over City.
Carvalhal had a close look at Liverpool just two days before taking over at the Liberty Stadium.
The Portuguese was at Anfield on Boxing Day when Swansea were thrashed 5-0 under Leon Britton's caretaker command.
