Hart hasn't made a save of note and has had just as many clangers as De Gea, wouldn't even be in my top 10. I should have went with Szczesny now I've had more time to think though.
Performance wise this season only, would be:
Szczensny, De Gea, Vorm, Krul, Ruddy and Al-Habsi any of these could be keeper of the year.
Next best: Hennessey, Howard, Mignolet, and Friedal.
Average: Hart, Cech, Reina, Given and Schwarzer
The rest: cba naming them
