Cardiff City defender Glenn Loovens is closing in on a move to Celtic after the club's agreed a fee for his services.
The Bluebirds accepted the fee, believed to be in the £2million to £2.5million region, after rejecting two earlier bids for the 24-year-old.
The news that The Bhoys have agreed a deal for the former Feyenoord man is a blow to Rangers' hopes of landing the defender, as they seek a replacement for Carlos Cuellar.
Celtic's interest had only emerged recently, but the addition of Loovens will give Gordon Strachan extra strength in defence, which was already a strong point of the champion's team.
Loovens could be earmarked for a central role alongside captain Stephen McManus, with Gary Caldwell moving out to right-back.
Celtic have already signed Georgios Samaras from Manchester City, Marc Crosas from Barcelona and Paddy McCourt from Derry City this summer.
"Glen Loovens has today been given permission to talk to Celtic," Cardiff chairman Peter Ridsdale told the club's official website.
"Glen made it clear that he would not discuss a new contract and that he wanted to move."
