Back up players is what we need, 3 back up players for each position ideally. Ones who aren't very good but CDAJFU if one of our XI gets injured. It worked really well when we were in the premier league in the 04/05 season where we had a massive squad full of average to crap players. Much better to follow this model than having 20-22 good players as part of the first team squad and some good youngesters who can be rotated depending on form, fitness, oppostion etc like all the top clubs do.
