What goalkeeper attribute determines the ability to deal with long shots?

I could have sworn there was a "shot stopping" attribute, but it appears i am wrong.

The defensive formation i play means that a lot of sides pepper my goal from far out - in my pre season games against the biggest teams in the world, they only score screamers from 30+ yds.

Which attributes should i look for in a keeper to save these thunderbolts?

on the top of my head : reflexes, anticipation, agility, jumping, positioning

aerial ability could well be included as well.
