ULTIMATE CHALLENGE
The dumbest mission ever, you win you will get 108ovr player, but your team losing percentage is 99%, how can the computer do a side step that only in dragonball Z character can do? That challenge ...
Are you talking about the Ultimate Weekend Challenge and the third game specifically? If so, it has been reported to the developers that the difficulty is ridiculous and has actually become worse with the new event.
However, you also do not need a fully trained and ranked team to beat it. The key is to move the ball around, keep possession, avoid sprinting or using skills, pass from the wing to a free player near the half circle (do not cross, pass on the deck!), usually your central attacking midfielder, then take a finesse shot. I can beat it with my childhood club squad (100 OVR and most are untrained and purple/red-ranked players).
