Diarra ..injured most of the season
Sadiki . Diarras replacement..been exceptional alongside Xhaka
Reinildo..left back
Traore and Talbi are the other starters
Masuaka also went does not start.
So 4 regular starters went to Afcon....and Ballard missing as our other regular starter.
Of the 5 missing.....
Traore and Talbi replaced by Mayenda and Adringa...slight impact
Sadiko repaced by Gertruuda.. impact
Reinildo replaced by Cirkin...major impact
Diarra and Masuaka n/a
Ballard replaced by Hume.... big impact..but more in who plays what position
So yes we are badly impacted.... but i would say in 3 instances of the 7..not all
