intensity

does the intensity that your players have on the training have affect on the matches?
first i won every match with 5-0 or 6-0, but the last 3 days my team have a hard time to score.
my players are top motivated and the conditions are 95+% too. i haven't change my formation.
my last 2 matches were against opponents with 14,1 and 14,8 quality, i have 27,9.
the only thing tha ti have changed is the intensity for the training (this because i'm power training a 18 y/o defender).
so therefor the question, does the intensity matters?

already sorry for my english

Hard intensity increases the risk of injury and the amount you gain from the sessions. It has no effect on the matches itself

ok, then it probably is just bad luck.... i just don't get it. from a minimum of 5 goals per match towards 1 or 2 goals per match. the only thing that changed are that and a new forward. i now have a 7 star and had a 5 star before. but my midfield always scored 2 or 3 goals per match so that must not affect it..... ok i'm going to try some things out...
