Yes, might be. But, I got two similar cases too. I think that my team have conceded way too many goals easily lately. The match ratings of most of the defenders has also gone down noticeably. The tactics I have used to face those two opponents are among the best to face what the they were using. The last one is even more anomalous as the opponent used a GK as MC, and yet, this weaker team scored 2 goals. Nik got one too, but he thought it was due to the bonus boost. Too many goals are being scored in a short time. These anomalies just started recently, like mid-week or so this week. If it is because of the recent changes made on some servers, you may experience the same too after the change is made on the server your account is.
