CELTIC have completed the deal to full-back Saidy Janko from Manchester United.
Reports first surfaced last week that Ronny Deila was looking to make the 19-year old his second summer signing.
Talks between Celtic, the player and his former club continued over the weekend, with the move eventually being confirmed today.
Janko joined United from FC Zurich two years ago in a £700,000 move, but has since been viewed as surplus to requirements at Old Trafford.
He spent the second half of last season playing under former Celtic boss Neil Lennon at Bolton.
The signing raises questions about the future of Adam Matthews, who has been linked with a move away from Parkhead.
Janko’s signing means there are currently three right-backs on Celtic’s books, though the new signing’s lack of experience, coupled with Matthews and Mikael Lustig’s injury problems, could mean there is a place for all of them in the 2015/16 Celtic squad.
