Middlesbrough have brought in teenager Josh Dede from Celtic on a permanent deal.
The 19-year-old, who can play right-back or right winger, will initially join up with Boro's under-21 squad.
He did not play for Celtic's first-team, but featured in their age-group sides as well as playing for Scotland Under-19s.
Dede is the fifth arrival on Teesside this month following Ryan Giles, George Edmundson, Morgan Whittaker and Mark Travers.
