yes, above 5 saves is unique and not very normal (meaning he was in a good day and even if you had more shots, he would make more saves - lol).
Also a 0-1 saves in an active game (vs a good oppo), its a bad game for your GK.
He 'll get a bad rate and you 'll get a bad result.
Then you 'll must observe the next 1-2 games.
Is he out of form ?
Or it was a parenthesis ?
