Hearts have completed their January transfer window business by signing John Souttar from Dundee United.
The highly rated Scotland U21 cap moves from Tannadice for an undisclosed fee, after penning a three-and-a-half-year deal at Tynecastle.
19-year-old John has made 73 appearances for the Terrors since making the first-team breakthrough in 2013 at the age of 16, which includes 21 outings this season.
Speaking to Hearts News, head coach Robbie Neilson said: “I’m really happy to get John here to Hearts.
“We see him as one of the brightest young prospects in Scotland, and one who we can develop further.
“John’s a player who we’ve admired for a long time and I’m delighted to secure him.
“It shows the intent of Hearts to not only develop young players from our own academy, but recruit them too and continue their development.”
