Daryl Murphy has made it clear that he didn't have to think twice about signing for Celtic once he heard Neil Lennon was keen on securing his services.
The 27-year-old has signed a three-year deal with the Bhoys after slipping out of the first-team picture at Sunderland, with Steve Bruce loaning him out to Ipswich Town last season.
Murphy admitted to Channel 67: "I haven't stopped grinning since I signed. This is massive thing for me and for my famiy.
"When I heard Celtic were interested there was only ever going to be one club that, given the chance, I would sign for.
"When I first heard the rumours I just took them with a pinch of salt but, as soon as I heard it was for real, I can't really describe the feeling because I'm probably the same as every other Irish lad.
"You always want to play for Celtic and nearly all of Ireland supports Celtic growing up so it's a massive, massive thing.
"My loan spells have made me hungrier and geared me up to play more. I want to come here and show the manager, the fans and everyone else at Celtic Football Club that I should be starting and hopefully I can do that early on.
"You have to work hard in training day-in and day-out and prove to the manager that you're worth a starting place.
"There are a lot of good strikers here that I'll have to battle with to make sure I'm in the starting line-up every week.
"There are massive expectations here and that's something you have to deal with as a player. If you can't deal with it though, you shouldn't be in the game."
Murphy joins fellow Bhoys newcomers Charlie Mulgrew, Joe Ledley and Cha Du-Ri in Lennon's squad ahead of the new Scottish Premier League season.
Murphy, who has won nine international caps for Republic of Ireland, started his career with Waterford United, before making the switch to the Black Cats in 2005, scoring 14 goals in 110 appearances for the club.
