Why do I get disconnects in the Weekend League when I win the game.

Dear EA Team, it now happend the 3rd Time this Year, that when i win a Game in Fut Champions I get the disconnect and the Loss in my Weekend League Standings. Last Week it happened immediately after the whistle was blown on my last penalty in a Penalty Shootout. I wrote to my opponent via PSN Messages and he even admited do disconnecting me. This Week(10 Min. ago) I shot the 2-0 at the 15th ingame Minute. My opponent paused the game and I got disconnected. It isnt my Internet, cause I keep talking to my Friends via Playstation Party and even Streams on my PC are still playing. And it would be a weird coincidence, that it only happens when I win, and only in Gamemodes where the Wins matter. I would love to know what I can do about that. Thanks.
