Yes, it may be luck to have 3 injuries in a match or none (in this game) but the whole injury system is NOT down to luck. It's Nordeu$ that programmed the game in that way so that your players get injured very often so you spend money to get red packs (and that's not the only dirty method Nordeu$ uses to get money). Now tell me, when did you saw a match in real life with a team having 3 injured players??
