Liverpool target Luis Diaz underwent his medicals in Argentina on Saturday evening as he closed on a £37million transfer from Porto.
The 25-year-old Colombia international, known as 'noodle' because of his wiry frame, is expected to sign a five year contract once he gets the all clear.
Liverpool made their move on Thursday after Tottenham's bid for the winger established that Porto would sell below Diaz's £66m buy out clause.
Liverpool are willing to offload Takumi Minamino, Divock Origi and Nat Phillips to help offset their spend on Diaz.
