Inter, Handanovic or Onana in goal? History of the alternation between goalkeepers

The alternation between numbers one is one of the recurring themes in football, an often harmful trend that repeats itself. Here are the most famous ballots

Inter goalkeepers (exchangeable). Handa out, Onana in. The choice of Simone Inzaghi (against Barcelona in the Champions League plays Onana) brings back to the center of the discussion the eternal dilemma about the goalkeeper to be considered one of the eleven or instead the +1 before / after the ten, or rather a separate element, to be considered and treat in its specificity. The question is: is it useful to alternate between goalkeepers?
