The same happend to me two seasons ago and El Pistolero blamed it on my lack of experience. Do not worry: I did not change a thing to my players and tactics and at the end, the logic prevailed. I won the league with a 15 pt margin. I think Nordeus take a list of teams randomly and decide to make their life difficult at some stage. Strangely, this happend to me at the same level... If your team is the best and your tactic adapted, you will win, whatever the others do (bad managers, good managers - experienced or not). Provided you attend the games and take care of your players. That's my opinion at least...
