The fault is of the game engine. I have experienced a sudden series of losses and draws against much weaker teams almost every season and I seem to have no reason or explanation 4 dat. I just go on losing and fall down in the table. Even this season I fell down to the 7th rank. Then the rough phase got over and I am 2nd now. So it depends when this chain of defeats will get over. When this time comes even morale and condition don't give a positive effect. Changing formations and tactics don't work as well. Neither do buying good new player cause any change. Sometimes It is the defence that doesn't seem to perform while the attack does, OTOH sometimes it is the vice-versa. Or sometimes the whole team starts underperforming. What ratings has your defence, midfield, forward and goalkeeper got when your team has lost recently???
