A former coach of Argentina has questioned Liverpool's decision to sign Luis Diaz in the January transfer window.
The 25-year-old made the move from Porto to Anfield last Sunday for a fee of £37.5million which could rise to £50m.
Diaz - who will wear the No 23 shirt at Liverpool - met Jurgen Klopp for the first time on Friday following international duty with Colombia.


But it was not a productive international break for the winger, who played the full 90 minutes in Colombia's 1-0 defeats by Peru and Argentina on Friday last week and on Tuesday this week respectively.
