The striker has signed a three-and-a-half-year deal at the Stadium of Shite, just days after he was booed by some of the Black Cats fans when he appeared against them for the Swans.
You have to laugh at the interview ...
Danny Graham: "As soon as I heard about the interest from Sunderland I didn't even have to consider any of the other options that were on the table.
"I was born and brought up in the north east so I know first-hand the intense passion that people have for their football in this part of the world - it's special and there's nowhere else like it.
"Of course, I totally understand that some fans might need convincing about my commitment to Sunderland because of my roots, but I've always given 100 per cent no matter what team I play for and no matter who I play against.
"It's up to me to show people I deserve to wear the Sunderland shirt, and I'm excited about playing for a club as big as this.
"I'm really excited about the future - this is a new phase of my career and I can't wait to get started."
The reaction on Tuesday night prompted former club Middlesbrough to make their own enquiry about Graham, but he wants to stay in the Premiership ... even if it is with Sunderland.
