"Every time I had holiday, I would go to England to see him.
Eder was born in the West African country of Guinea-Bissau but moved to Portugal when he was a toddler.
"I came to Portugal with my mum from Guinea-Bissau," he said.
"My dad was already in Portugal. There was a moment when my dad came to my mum's house and ended up taking me with him and I went to live for some time with my dad. After that I was put into the college."
Ederzito Antonio Macedo Lopes, 28, has recently joined french side Lille after spending a season with English Premier League side Swansea City.
He scored the winning goal for his national side in the recently concluded Euro 2016 final against final in the extra-time.
Speaking more about his personal life, Eder said: "I have a sister studying in Wolverhampton and I have another sister who has lived in England for a time.
"My brother lives in Portugal, but I have family everywhere.
"I didn't really grow up with my family. I grew up in a college.
"It was really good for me. It helped me to grow into the man that I have become and aided my football career.
"Of course, at times it was a little bit tough, which is normal, but I enjoyed it a lot. I met so many of my friends there, and it was good to have that life experience."
