In terms of age distribution, I don't think midfield was as big an issue as some made out.
Bentancur 28, Palhinha 30, Bissouma 29, Sarr 23, Gallagher 26 brought in in Jan for 2 positions and then Gray and Bergvall as the younger options. Problem is half those senior players aren't reliable, Bentancur misses large parts of every season, Bissouma both injury and discipline problems plus both him and Sarr had to go off to AFCON, Sarr wasn't quite the same after the opening handful of games and Gallagher didn't exactly hit the ground running. Defo agree we've had to rely on them too much, particularly in the most injury hit periods when it's probably the hardest for them to make an impact in a weakened side.
