Chelsea have one of the best youth academies in the world, and are known for loaning out 30 to 40 youngsters a season in order to develop them.
They have built up partnerships with sides so they can loan there youngsters to them, with the guarantee they will get game time and be developed.
Whilst Mourinho was at the helm, there was a relationship with Middlesbrough as the two men worked with each other at Real Madrid and had built together a striking friendship.
Karanka has often taking advantage of this friendship loaning several young players from Chelsea such as defender Kenneth Omeruo, defender Tomas Kalas and most notably striker Patrick Bamford.
Bamford was a wonderful acquisition for Middlesbrough last season and his 19 goals nearly led Middlesbrough to the Premier League, but they fell short in the play-off final with a 2-0 defeat to Norwich.
But Bamford picked up Championship Player of the Season and left Middlesbrough with the fans’ admiration.
Middlesbrough have followed up last season’s success with a spending spree, as owner Steve Gibson tries to force through the side’s promotion and with the signings of Gaston Ramirez, Ritchie De Laet, Christian Stuani and David Nugent they look a better side than last year.
But there most notable signing by far was gaining the signature of Blackburn striker Jordan Rhodes, who was bought recently and with his impressive goal scoring record, could be just what Middlesbrough need in the promotion run in.
They are going well at the moment and sit top of the table but are going through a difficult patch of results and may look into the emergency loan window for players, and Karanka has said that he may look for defensive cover due to the recent injuries to key defenders George Friend and Daniel Ayala.
Middlesbrough have the best defence in the league and will want to protect that status.
Here are THREE Chelsea players Middlesbrough could sign in the emergency loan window…………….
