Well i have quite a few important matches in the league and CL and one of my best players just got injured with 6 days to go. He is avg quality 25 with 20 def 31atk 27 mental or the sort, plus playmaker SA. Currently 21 years old and 1.12M value. medium to high power trainer. Should i sell him and buy a short term replacement? (i do need a replacement cuz i really have to win the last few games in the league)
