Gameplay

So yesterday I've played 1 match and the gameplay was super smooth, fast paced as I like it, today all my players can't run anymore, can't pass the ball, can't intercept, feel slow on ball, can't dribble, no reaction and gameplay feels heavy and slow (91 squad rated feels like bronze cards).

I've got this problem even in Squad Battles as my team may be 91 rated but feels more like the weak teams from this gamemode. 

Why is this happening and is it a connection issue? 

Thanks for help.
