How would you rank them. I'd go with....

1. Thibaut Courtois
2. Petr Cech
3. Hugo Lloris
4. Tim Howard
5. David De Gea
6. Asmir Begovic
7. Joe Hart
8. Simon Mignolet
9. David Ospina
10. Wojiech Szczesny
11. Kasper Schmeichel
12. Tim Krul
13. Willy Cabellero
14. Julian Speroni
15. Adrian
16. Brad Guzan
17. Mark Schwarzer
18. Ben Foster
19. Vito Mannonw
20. Lukasz Fabianski

Caballero so low? Ridiculous. He's better than both Begovic and Hart. He should be somewhere between 4-6. Only Courtois, Cech, and Lloris are outright better than him.

My top 10 would be,

1. Cech
2. Lloris
3. De Gea
4. Courtois
5. Caballero
6. Howard
7. Begovic
8. Szczesny
9. Mignolet
10. Krul
11. Schmeichel

1. De Gea
2. Courtois
3. Cech
4. Lloris
5. Hart
6. Caballero
7. Begovic
8. Szczesny
9. Howard
10. Mignolet
