Liverpool attacker Luis Diaz has released a statement pleading with kidnappers to release his father.
Diaz returned to the pitch on Sunday and scored in Liverpool's 1-1 draw at Luton.
Afterwards, the Colombian released a statement to the National Liberation Army (ELN) who are holding his father, Luis Manuel.
"Every second, every minute our anxiety grows," Díaz, 26, said in a statement released shortly after the match.
"My mother, my brothers and I are desperate, anxious and have no words to describe what we are feeling. This suffering will only end when we have him home with us.
"I beg that they free him immediately, respecting his integrity and ending this painful wait. In the name of love and compassion we ask they reconsider their actions and allow us to have him back."
Díaz also thanked "the Colombians and the international community for the support that's been received, [and the] many demonstrations of care and solidarity in this difficult moment".
