Liverpool's interest in Luis Diaz should come as no surprise as manager Jurgen Klopp has already expressed how closely he watches the Portuguese league.
The Reds are understood to be pursuing a deal potentially worth up to £49m for Diaz as they face a race against time to get it done before Monday's transfer deadline.
The Colombia international already has 16 goals for Porto in all competitions so far this season as his side currently sit top of the Primeira Liga.
