Celtic have completed the signing of Willo Flood on a two-and-a-half-year contract.
The midfielder talks with the Clydesdale Bank Premier League champions less than 24 hours after his penalty miss helped send the club into the Co-operative Insurance Cup final at the expense of Dundee United.
"It really is a tremendous honour to sign for a club of Celtic's stature," Flood told www.celticfc.net.
Celtic agreed an undisclosed fee with Cardiff for the 23-year-old, who spent 18 months on loan at Tannadice.
Flood hit out at Celtic over the "stupid" transfer speculation immediately after Wednesday's semi-final at Hampden but his "dream" move soon materialised.
The Irishman, who began his career at Manchester City, revealed his pride over signing for the Hoops.
He added: "This is an exciting challenge and one which I am really looking forward to.
"I have been a fan of Celtic all my life and this truly is a dream come true to sign for the club.
"I will be joining a great group of players and I will be giving everything I can to make as big a contribution as possible to Celtic Football Club.
"I hope to play my part in achieving more and more success for the club and its supporters."
