How can I dominate the lose?

I was playing someone of fc25 ultimate team rivals I was the better player throughout the game but then all of a sudden they score 1 and then end up scoring 4 all of a sudden my defense wasn't responding my team lost all there pace from the 75th minute why does the game do this? Now I know the reason but I'm not allowed to say as I'll just get banned for mentioning it I think we all know what I'm on about but I want an ea advisor to explain why this happens? Why all of a sudden the game just gifts my opponents goals it's incredibly strange.... Please ea explain how this happens? I was the better player it happens alot in fc25 and the issue hasn't been addressed.
