Sadio Mane says he "knows how good" new Liverpool signing Luis Diaz is after the Colombian's arrival at Anfield has added extra competition for a place in the Reds' first XI.
Liverpool signed Diaz in the final hours of the January transfer deal for an initial fee of £37.5million which could rise to £50m depending on performance-related add-ons.
And Mane has responded to the arrival of the new signing at the club, which happened while he was winning the Africa Cup of Nations with Senegal.
