Chelsea boss Jose Mourinho reckons they've signed something special in Bertrand Traore.

Traore, an attacking midfielder, joins from Association Jeunes Espoirs De Bobo-Dioulasso and is a full international for Burkina Faso.

He made his debut in September 2011, a few days before his 16th birthday, and made one substitute appearance at the 2012 Africa Cup of Nations.

"Traore is a great talent that the club followed for a long time before me," Mourinho said.

"I wanted to take him to pre-season to have a view of him for two or three weeks and play him in front of 60,000 to 80,000 crowds like we have in Asia.

"Now we could get him. We have a kid who in our opinion is one of the best talents of his age. I think he is ready to make an impact."
