Just have one as a backup in case he gets injured in the 5th minute or something.. I always have a 2nd keeper on my bench, you never know when it'll come in handy
i have only one GK .. with no problem
he got injured at 20 min, played a CB as GK, and had a clean sheet
that is how much engine $ucks
as long as he defensive ability is good, he will be great GK even if he is a defender
