The Ghana midfielder admits he endured a difficult time at Dnipro in Ukraine.
He told the Fulham Chronicle: "I wasn't happy there. I was living alone without my family, which was very tough for me. I explained it to Dnipro several times, but they didn't understand.
"I really love my family and want them beside me all of the time. They give me more energy and power to keep going. I cannot survive without them. I only got to see my kids when they had vacation in school. I would see them for two weeks and then they would go. It was really tough.
"Fulham were interested a few years ago. There was a misunderstanding with Dnipro. Fulham really wanted me to come but they said no. I wanted to go. I always had Fulham in my head - that was the club I wanted to play for.
"It's a big relief for me to finally be here. This is the third time they've come in for me, so I thank God it's happened."
