Sunderland striker Daryl Murphy has completed his move to Celtic.
The 27-year-old has joined the Parkhead club on a three-year-deal.
He was manager Neil Lennon's fourth signing of the summer, following the captures of Charlie Mulgrew, Joe Ledley and Cha Du-Ri.
Murphy began his football career with his hometown club, Waterford United, before joining Sunderland in 2005.
He also had loan spells at Sheffield Wednesday and then Ipswich Town last season.
Murphy insists he can be first-choice striker at Celtic - despite failing to hold down a place at Sunderland.
"We want to win, that's the main objective here," he said. "I also want to stake a claim to be first choice striker, that's my first aim.
"It's going to be hard because there are some good strikers here but that's the first thing I need to do, make sure the manager wants me to be his number one.
"That's what I've come here to hopefully achieve.
"I just want to get into the team as quickly as possible.
"It's going to be hard work but I think if I put in the work and the effort - which I will do - hopefully I can start every game and play a big part in winning the title.
"I've been used as a left-midfielder quite a lot in my career, which is not my position, it's a centre-forward.
"I know, if given the chance to play as a striker and a run of games, I can score goals, especially in a team like Celtic who will be attacking a lot."
