Rain/Shower affect the match at all?

Does rain/showers affect the match at all? I tried putting my players on taking long shots to often and play a short passing game. It seems to look like they play the same on dry and sunny days. No Robert Green fumbles.

I was always under the impression that this had more of an effect on the player fatigue, rather than the ball movement, in that sodden grass takes more effort to run on. I could be wrong though.

It deffo affects ball movement too. In heavy rain I've seen the ball almost come to a halt when passed. As if there were puddles on the pitch.
