I always player career mode and the AI is frustrating as hell this year. Your pacy striker/winger can be through on goal and five yards ahead of the defender but theu will always catch you and always win the ball. The same with the keeper rushing out and diving at your players feet, they always get the ball.
Something I find amusing, decided to go AC Milan and managed to get Anthony Martial on a pre season contract for my second season, every time he scores a goal the Milan fans (who have been singing in Italian the whole game), start singing some song about Martial in a Manchester accent
