3 former Manchester United players with buy back clauses

#2 Adnan Januzaj

Adnan Januzaj impressed greatly at Old Trafford before moving to Spain

Having joined Manchester United at the age of 16, Januzaj spent a total of six years at Old Trafford before moving on a permanent deal to Spain. The young Belgian impressed United scouts during a skills session in Brussels and swiftly moved from Anderlecht to Old Trafford where he spent two seasons playing for the Manchester United youth team.

However, at only 18 years old, he caught the eye of Sir Alex Ferguson and was promoted to the first team where he sat on the bench for Fergie's last game as United manager against West Brown. It was under the United legend's successor - David Moyes, that Januzaj really impressed.

The Belgian made his Premier League debut under Moyes and played regularly throughout the 2013-14 season, earning many plaudits. However, after Moyes' failed tenure at Old Trafford, Januzaj began to struggle under Louis Van Gaal and fell out of favor. In 2015 he was loaned to Borussia Dortmund, and in 2016 he went on loan to Sunderland.

Following these loan spells, Mourinho made the decision to sell Januzaj to the Spanish club, Real Sociedad. However, once again United inserted a buy-back clause for a very promising player who was still young and had huge potential.

Since moving to Real Sociedad, Januzaj has played regularly and shown glimpses of the talent which made him one of the most highly rated teenagers in the world. He also played and scored for Belgium in the World Cup, curling in a wonderful goal against England.

Should his form continue, a return ticket to Old Trafford is a distinct possibility for the 23 year old.
