Liverpool have already been provided an indication of what to expect from Luis Diaz, having twice faced the Colombian this season in the Champions League.
Diaz completed 90 minutes of action at both Anfield and the Estadio do Dragao as Jurgen Klopp's side earned two routine victories against their Portuguese opponents on their way to top spot in Group B.
As well as facing off against the 25-year-old at club level, one member of the Reds' squad has gained a closer look at the forward on the international stage.
