Subject: short keeper

I found a younger keeper to replace my 29 yo, but this guy has 1,68m
isn't too short? does it matter?

It doesnt matter. Height has miniscule effect on performance.

Ellison is very short with superdivine pace, I think it actually helps, keepers only move in short bursts, so they rarely use all of their pace, but if they have great acceleration because they are short then they move around a bit better, Razor has made some amazing second and third saves because of his pace
