should goalkeeper injuries be more common?

only once have my GK picked up an in match injury (Kanu the goalkeeper was superb) over what is roughly 5 sessions with different teams on fm11.

on fm10 i can only recall 2-3 in match injuries in what i would estimate was 30 sessions with different teams, never once have any of my keepers been knocked out for longer then a few days to 3 weeks unless it was a pre set injury included in the db

all this have made me think its just best to stick 7 outfield players on the bench, the risk of the GK geting hurt is simply so low that the extra options provided by one more outfield player pay of far more...in short this just dont feel right, and you will never need a 3rd chose goalie on this game
