Liverpool new boy Luis Diaz declared he will "give absolutely everything" to make the Anfield faithful proud as he was officially unveiled on Friday.
Diaz, 25, joined the Reds from Porto in a surprise transfer at the end of the January window for an initial fee of £37.5million which could rise to £50million with add-ons.
The highly-regarded winger was away with the Colombia national team at the time of his signing but touched down on Merseyside on Thursday.
