I bought 117 van der sar and has great stat but every shot is a goal

Where did you buy him mate.. afaik the max available on market is 109.  Did you go for the Toty box?

If yes, have patience..  usually they get better.  Also rank him up.  He was the best GK around for a while apart from VMS. But a bit silly to buy him if u had courtois in my opinion.
