Celtic have signed Daryl Murphy from Sunderland on a three-year contract, the club has confirmed.
The Republic of Ireland international becomes the Hoops' fourth signing of the summer transfer window after Charlie Mulgrew, Joe Ledley and Cha Du-Ri's arrivals at Parkhead.
Murphy joined Sunderland in 2005 and has since had loan spells with Sheffield Wednesday and Ipswich.
He scored five goals in 18 appearances for Town at the back end of last season after a much shorter stint with the Owls before that.
The 27-year-old made his full international debut in May 2007 against Ecuador, his first of nine caps for his country to date.
Murphy admits he had no hesitation in quitting Sunderland for Celtic once he learned of their interest.
Asked why he joined the Hoops, he said: "I don't even know where to start.
"Being Irish, I grew up with Celtic everywhere and as a kid I supported them.
"The club's history, the fans - there are a million reasons why I joined."
Murphy is unliklye to join up with his new team-mates on their pre-season tour of North America, but is delighted to be a Celtic player.
He added: "The first I heard about their interest was about a month ago but at the time I thought it was just speculation in the papers and didn't read too much into it.
"Over the last few weeks I found out it was concrete and it's happened quite fast. I'm just happy to be here."
