Celtic have completed the signing of Dutch defender Jos Hooiveld on a three-and-a-half-year contract.
The 26-year-old is the Hoops' first signing of January. He has joined from Swedish club AIK Solna for a fee of around £2 million.
Hooiveld told the Hoops' official website that he's "delighted" to have signed for Celtic.
And Celtic boss Tony Mowbray said he was thrilled with the news: "We are very pleased to welcome Jos to Celtic."
"He is a player who we believe can make an important contribution to the club and someone we look forward to working with."
Jos Hooiveld will be moving from AIK Solna, where he has played for a season.
Previously he's played for Inter Turku in Finland, Austrian side Kapfenberger and Heerenveen in the Netherlands.
