#6 Thibaut Courtois - Chelsea
Once considered one of the best in the world, Thibaut Courtois has seen his star fall over the last few years, as the Belgian has struggled with consistency - looking nigh on unbeatable in a few games, while also having far more frequent moments of nervous handling.
Perhaps uncertainty over his future is playing a part - Courtois' contract runs out at the end of next season - and he has put talks with Chelsea on hold. Conte is in no doubt about the Belgian's quality, though, saying "I consider him one of the best. For sure, he will be the best in the world, maybe he is now the best. But, for sure, in the future, he will be the best goalkeeper."
When a man who's coached Gigi Buffon for quite a while has those words to say, you tend to agree - Courtois will not stay at #6 for long. The Belgian has begun to look his old self in the 2017/18 season, and things are on the upswing.
