5 straight defeat!! Is Nordeus trying to kill me??

[Yen N Yik]

Hi guys..
Recently my team suffered 5 straight defeat!! At the beginning of the season it's still ok and my team can climb up to top of the league in mid-season. But after that look what I get... 5 straight defeat including a cup final!!
I just don;t understand. I have the same bunch of players when I'm no.1 in my league... Does no changes to players and tactics bad to my team?? how come they perform badly suddenly?? Striker can't score goals... defender can't defend and goalkeeper can't save!!
