Today, my team spent 30 red packs to heal a MC because he consecutively received 6 days injuries in a match and then in training.
This midfielder is not very good. I tried to sell him but failed. He's almost impossible to be sold now because he just reach a new star level & he's not young (26). In fact, I can let him rest tmr because there will only be 1 match tmr. However, if I let him to recover on 2 days later, I will still spend 14 red packs, and the player condition will reduce in these 2 days. So I still painfully heal him with 15 red packs, well, for twice!
