Craig Levein has bolstered his squad with the loan signing of Demetri Mitchell from Manchester United.
The highly rated left-back, who turns 21 today, joins the Jambos until the end of the season, subject to international clearance.
The Manchester-born defender signed for United at the age of 10 and has amassed numerous international caps for England at youth level. He boasts both offensive and defensive qualities, having converted from a winger to a defender last season.
Demetri was handed his senior Manchester United debut by Jose Mourinho in a Premiership match against Crystal Palace on the final day of last season.
He will fly out to Spain tomorrow to join up with his new Hearts teammates at their training camp in Valencia.
