Why is David De Gea so poor in SWOS

I have recently tried playing SWOS as Manchester United, but it is virtually impossible to win any games as David De Gea is unbelievably poor despite being rated as 4 stars.

When playing against any top European club he fails to make a single save when a shot is on target and only barely improves when playing against lower quality opposition (makes approximately 2 saves against every 10 shots). He is worse than keepers rated as 1 star and even worse than Claudio Bravo for Manchester City IRL last season!!!!!

I even tested this by running matches in CPU vs CPU mode and the results are still the same. I don t notice this performance from any other keepers of a similar rating in the game against similar opposition.

Why is he so poor in comparison to other keepers?

(oh i m using the 17/18 update that was available BTW)
