Celtic have announced the signing of Boli Bolingoli-Mbombo from Rapid Vienna.
The 24-year-old Belgian defender has joined the Scottish champions on a four-year deal.
He becomes Neil Lennon's third signing of the summer following the arrivals of Christopher Jullien and Luca Connell.
"It feels amazing to be part of the Celtic family," said Bolingoli-Mbombo.
"I am happy to be here and hopefully I can help the club win more titles and trophies.
"You cannot say no to a club like Celtic. It is a great opportunity for me to take the next step."
Bolingoli-Mbombo started his career with Club Brugge before moving to Rapid Vienna.
He made 73 appearances for the Austrian club, scoring four times.
Celtic begin their Champions League qualifying campaign against FK Sarajevo in Bosnia on Tuesday.
