In my case, I always get a ridiculous amount of cards early in the season. Then, it usually cools down a bit. It may be really annoying in tough cup games: I got a red card + penalty at 17th minute the other day that completely ruined my good start (stat-wise). Ended-up 0-1 as we are not in the old days anymore when you could be sure that getting down to ten will mean a goal for you in the following minutes.
