It seems as though you only started following football since the lockdown.
Early stages of CL have many easy games that allow for squad rotation, we don't have to win every single game when we play during those sequences, the squad will have a different spread of fitness/recovery amongst the players, we'll have a stronger squad because of incoming transfers.
Many more reasons I cant be arsed to write, because it's all so obvious, unless you only started following football since the lockdown, in which case watch more football and learn.
Lastly, we wont have the conundrum you write about if we don't get CL football next year, so your whole premise is rather pointless too.
Your stance reminds me of the redcafe infamous words of
@GlastonSpur 'want, Want, WANT'.
