Celtic have clinched the signing of defender Glenn Loovens from Cardiff on a four-year deal.
The Scottish Premier League champions have been tracking the defender for much of the summer and agreed an undisclosed fee with the Bluebirds earlier this week.
The move has now been finalised and Loovens becomes Gordon Strachan's fourth signing of the summer following the arrivals of Georgios Samaras, Pat McCourt and Mark Crosas.
The 24-year-old has expressed his delight at the transfer and is now looking to make a big impact at Celtic.
"It really is a tremendous honour to sign for a club of Celtic's stature," Loovens told the club's official website.
"I am really looking forward to playing for a team that has such an incredible history and well-known and passionate supporters.
"The club has enjoyed great success in recent years, winning titles and cups in Scotland and doing well in the Champions League.
"I am looking forward to the challenges here and hope to play my part in further honours."
Loovens had been a long-time target of Rangers but opted to join their fierce
rivals so he can play in the UEFA Champions League this season.
