Defender Gary Caldwell has officially been unveiled as a Celtic player, as Gordon Strachan continues to reshape his squad.
The 24-year-old Hibernian captain signed a pre-contract agreement with The Bhoys in January, and has now completed his move to Parkhead on a Bosman free transfer.
He will join up with fellow Scotland international Kenny Miller, and former Hibernian team-mate Derek Riordan in the winter.
Celtic chief executive Peter Lawwell has hailed the latest cheap Strachan summer signing.
"Gordon had watched him and Tommy Burns was close to him for a number of years with Scotland," Lawwell revealed.
"He was somebody we had as a high priority to get him here and we are delighted to get him in such circumstances.
"We would hope to strengthen more and Gary is part of that."
The former Newcastle United youngster had a tricky time at Easter Road when details of his preliminary deal with The Hoops came out, but he has not been fazed by the pressure.
"It was difficult but I am sure that will make me stronger and a better player," Caldwell stated.
"In the long run that will help me, and Celtic will see the benefits of that."
