Career mode (FIFA 19)

Hello! The problem is... choose a strong team, start a career in Manager mode. Difficulty - world class (so it seems I do not remember exactly), 10-15 of the matches the team plays nice, normal run... then all cardinally changing, team-outsiders start to run much faster.. my defenders can't catch up with their forwards and my forwards can't run away from defenders on one meter (although skill jerks and the speed is 90). Gone quick attack ... now my attackers somehow run backwards instead of forwards and defenders, the attack of the opponent are smoked bamboo... 3-4 times for the game from three meters normally get in the gate (then past, then just in the hands of the goalkeeper) the ball flies slower than running defence... What happened to the team???
