Why do you think I'm "looking for excuses"? The best team won on the day. We just didn't give ourselves the best possible chance by not picking the best possible team (in my opinion).
It was clearly a case of Pep overthinking it rather than going for the obvious (and best) line-ups, as he has done so often in the Champions League. One of the things elite sportspeople want is to be as close to being in their comfort zone as possible. Picking that team (specifically Gundogan as CDM) put people out of their comfort zone immediately as it came totally out of left field. We managed to get to the final last season precisely because Pep hadn't fucked about in the quarters and semis.
As for your potential starting line-ups above, so you've compared the actual starting line-up with two teams that nobody would have dreamt up in a million years (Steffen, Mendy, Ake etc). Not sure what point you're trying to prove with that but it isn't a good one.
