This is one of the most common and high frequency problems in fut 20... Disconnections! It's happening to me 2-3-4 times every week, but I have to be thankful, cause, other FIFA FUT 20 fans, as they wrote me, counted 5 to 10 disconnections per week!! The most sadistic way is when the referee has finished the game! A game you have won, but.... EA servers God has different opinion. You reading the message "you are disconnected..." and you know that a 0-3 and a big ZERO points is waiting for you.... Even when that message pop up: "the EA servers are unable to process your request at the current moment. Please try later', where it says clearly that it is EA servers problem, it is also we who be punished... 

Have a nice time
