Fc mobile.Game play

Hello. So i have noticed my game play has changed, just last week I was wining games with a 4-0 wining 3 games out of 5 and game play was smooth, flowing with a flowing tiki taka play, this week it's been a constant loss 4 out 5 games loss. And I can't do any organised plays, I just get beat  or defence is constantly manned before my players get there but mine are all in the mid field. Also I encounter a cross spamer that which their game play was constant with the cross manouver.  

Am I doing something wrong or is scripted at work.  No formations make any difference i even changed some players. This all H2H matches all other A.i matches are ok.
