I can understand the frustration of some player, but real life soccer is the same. Sometime team sign great player that do **** on their team( there is a bunch of parameter , tactics, teammate , form, personal preferences....) some team on paper look ten times better than the other and draw/ loose against smaller ( less talented team). Even the signing( bidding here ) go wrong sometime for whatever reason. Injuries too,some team have more than their share ( even if Nordeus exaggerate quiet a bit on that subject) if it is intended to reflect real life soccer , then yes it is a good simulation and team with more money are advantaged ( even by the referee) even the cup draw in real soccer are sometime questionable.
Some players think that buying like crazy will get them only victories ( personally I think it s boring .... Like being Barcelona's fan)there is just few crazy things to be adjusted in the game but overall it s entertaining as a game is intented too!!!
And real life soccer is also spoiled with money. I regret the soccer from the Seventies/ Eighties it was still a sport at that time.
