This is a post I made a season ago, when rating goalkeepers
01. Mignolet
02. Asmir Begovic
03. Joe Hart
04. Michel Vorm
05. Julio Caesar
06. John Ruddy
07. Ben Foster
08. Petr Cech
09. Tim Krul
10. Tim Howard
11. Brad Friedal
12. Pepe Reina
13. Brad Guzan
14. Jussi Jääskeläinen
15. David De Gea
16. Ali Al Habsi
17. Adam Federici
18. Mark Schwarzer
19. Wojciech Szczesny
20. Kelvin Davis
For the sake of comparison, and how watching more of them, and their form, changes my ratings.
01. Courtois (brilliant goalkeeper overall) *not ranked previously
02. Lloris (quickest, smartest goalkeeper I can remember. Genuinely great at most other aspects as well) *not ranked previously
03. Begovic (fantastic shot-stopper, good cross-collector) *down 1 from 2
04. Cech (great solid goalkeeper overall, had a much better year, like his old self) *up 4 from 8, after he had those couple of wobbly seasons after his head accident
05. Mignolet (down 4. Difficult first season adapting to Liverpool and increasing demands on his distribution, still a class act shot-stopper) *down 4 from 1
06. Vorm *down 2 from 4
07. Howard (great year for Howard, was sensational at the WC too, always been a top 10 gk) *up 3 from 10
08. De Gea (he's got passed the stage of being a perpetual baffoon, and has become a pretty reliable keeper. Best distribution from a keeper I've ever seen) *up 7 from 15
09. Wojciech Szczęsny (had an exceptional year. would have broken the top 5 easily, had he not succumbed to bouts of rashness again in the latter half of the year. Massive overall improvement which pleasantly surprised me) *up 10 from 19
10. Ben Foster *down 3 from 7
11. Mannone *not ranked previously
12. Krul (poor season by his standards. His wife has given birth, he's had his head in the clouds, and had only one great game, vs Spurs. Highlight, though was as pen hero for the Dutch, when his record at saving pens for us is s****!!!!) *down 3 from 9.
13. Guzan (solid keeper, always has a good game) *no change
14. Jussi *no change
15. Boruc *not ranked previously
16. Schmeichel (think he will move up the list if City stay up, not expecting that though. He's a very good young keeper, who's been around a bit. Defo worthy of his shot in the big-time at last. Not a patch on his dad, however) *not ranked previously
17. McGregor *not ranked previously
18. Heaton (put in some decent displays in the championship, but expect him to be found out in the prem) *not ranked previously
19. Rob Green (Never been a fan of Rob Green. He has one decent season several years ago, and got into the England squad until someone decided to give him a game

He's one of the flappers. These are the worst breed of goalkeeper. They palm the shot into areas where attackers are, instead of catching the ball, they flap on collecting crosses, and usually flap at punches) *not ranked previously
20. Speroni (He's had some good games, but the pj keeper has had several howlers along the way, and just isn't up to prem standards in my opinion) *not ranked previously
