Liverpool manager Jurgen Klopp took time out of his holiday to ensure the club completed the signing of Luis Diaz last month.
The Reds signed the Colombia international, 25, late in the January transfer window after agreeing an initial £37.5million fee with Porto.
Diaz enjoyed a superb start to the season in Portugal, scoring 14 goals in 18 Primeira Liga games to help Porto reach the top of the table.
