The Ghana international recently left the Stadium of Light to take up a season-long loan in the Middle East and although he has received plenty of criticism for the way he went about it, Gyan insists that the Black Cats could have kept him and added that it was a move that all involved were happy with.
"I did not have any problem with Steve Bruce. He is a great coach and he has always supported me," Gyan said.
"People say I moved because of money.
"You need to be happy - although I'm not saying I wasn't happy at Sunderland or I wasn't happy in the Premier League.
"I had to decide with my family and everything and they were alright with my decision so I had to just move.
"I think the three parties were happy to do the deal."
