the players are too heavy ,can't do anything probably , slow motion animation

Hello Guys 

i have an issue from the last season which made me can't compete at all .

the gameplay is to heavy comparing with opponents who move faster and act better clearly , i do everything in slow motion which make the opponent have advantage on the ball in every single action , even the game AI does not working probably , the player could not do positioning , even can't shot in front of goal because during the animation of shot the opponent defender come from far distance and take the ball , that makes me so disappointed with the game and affect my mental health so much , and the heavy actions get my arms burn from just couple of matches , i did all the troubleshoots you advised but no difference , i need a solution guys to compete fairly and stop the hummelating that happening  the field because some unrespectful players use that on me , i wish you take my case into your considering and waiting for your quick response , thanks
