2. Thibaut Courtois
The Belgian goalkeeper is one of the best shotstoppers in the world and the way he is improving, he can be the greatest keeper in the world in some years. And to think that Chelsea got him for £7.9 million was a steal. He was transferred from Genk to Chelsea, but he spent three seasons at Atletico Madrid and that is where he vastly improved as a player. Chelsea recalled him this season and now he is the starter ahead of Cech. The 22 year old has already attracted the attention of the football world and under Mourinho he can only grow as a player.
