6. Thibaut Courtois Chelsea
The Belgium goalkeeper is currently on loan at Atletico Madrid following an impressive spell at the Vicente Calderon last season, when the Spanish side won their second Europa League trophy in three years. Seen as the long term replacement for Petr Cech, the shot-stopper has the characteristics to make a great Premier League keeper. He exudes confidence and shows maturity far beyond his years. The 20-year-old only missed one La Liga game last season and in those 37 matches he kept 15 clean sheets. The experience he is gaining as a regular at one of the biggest European clubs is invaluable and at his age he has many, many years ahead of him.
