Last season it happened to me, in the 2nd ROUND of LEAGUE i just wasent able to win, just end in 9th place, like me the team that ended in 8th place, we have similar quality.

This season, same players, same formations, me and the other team are in same LEAGUE again and we are both confortable in top 4.

Just set a formation and stick with it during 2/3 games, same players, just to see If you spot the bad performers, then bench them.
Try reliable formations like 442 or 4411 or any other not to ofensive.

Sometimes you just need to forget a season and restart in the next one.
