Celtic have signed Sheffield Wednesday defender Osaze Urhoghide on a four-year deal.
The highly-rated 20-year-old becomes the first new signing of the Ange Postecoglou era.
Record Sport exclusively revealed earlier on Thursday that Urhoghide was set to join former Owls team-mate Liam Shaw in the Scottish Premiership.
Postecoglou insists Celtic have landed a "modern defender" with all the attributes to become a top player.
He said: “It’s great. He’s someone that the club’s been tracking for a while and when I came on board, I managed to have a meeting with him and he’s a good young man, he’s very ambitious.
“He’s just beginning his football career but he shows all the attributes on and off the field to want to become a top player, so it’s great to get him here. He can play a couple of positions at the back and, most importantly, he’s really keen to learn and develop and I think this will be a great environment for him.
“He’s a modern defender. He’s good athletically, he’s mobile, he’s quick and he wants to get on the ball. He can play a couple of different positions, and from our perspective, and the way we want to play our football, there are certain things I look for in players irrespective of age, and he’s got some really good attributes to be a top defender.
“The most important thing is, he’s got a real desire to reach the very top. He’s excited about joining the club, which is important to me because that’s the first thing I want to hear from players, that they’re really keen to join us.”
