another side of him being in the line up as a midfielder which aint a great fit for him:
it leaves us without a striker on the bench, which is usually the number 1 substitution at all other clubs when a goal is needed, bring on another striker or replace the struggling/injured striker.
imagine a big CL game needing a goal to go next round, Alvarez starts as midfielder, subbed off at 60 min due to similar display to todays, 70. minute Haaland injured, we have no one upfront really and needing and our CL fate is on the line going into extra time/pen shootout without a striker.
it all stems from not replacing Gundogan properly.
