Celtic have confirmed the signing of Shane Duffy from Brighton on a season-long loan.
The centre-back is currently on international duty as Ireland prepare for the first games of the Stephen Kenny era against Bulgaria and Finland.
"I really am delighted to sign this deal with Celtic," Duffy told the club's website.
"It is a huge honour for me to join Celtic, such a huge institution and a brilliant football club that I have always loved and admired
"It will be a fantastic personal moment for me when I pull on the Celtic jersey. It’s just a great feeling – I could not be happier to be part of the club now and I just can’t wait to start working with the manager, the staff and the players when I return from international duty with Ireland.
"We will be challenging on a lot of fronts this season and I am really excited about getting going, as we try and bring the fans more and more success."
Celtic manager Neil Lennon said the club signed Duffy despite interest from Premier League clubs.
"We are delighted to bring a player of Shane’s quality to Celtic," said Lennon.
"He is an international player with so many great attributes. He is leader and he’s a warrior – someone with real ability and who will also give us that great physical presence.
"I know too he is a player who will add great personality to the dressing room. This is a real coup for the Club. From the off, Shane wanted to come to Celtic and we are delighted we have been able to fend off English Premier League interest."
