What about the run in 2018/19 incredible intensity , having to play every 3 days, having to win every game, muck or bust.We weren't tired, just economical because the game with Bayern and then the final would have required enormous physical efforts on our part.
Since we have obvious problems at CB, we are at our best when we defend from the front like we did vs Madrid. But that's an energy very demanding way of defending and we can't do it every 4 days.
I wish Pep had experimented with Walker at CB. But the experiment might have been disastrous. The problem with Walker is that his awareness and positional discipline are not his strongest sides and they are crucial for CBs. It was Walker who played Lyon's forward on for the first goal and it was him who nearly gave a pen away in the 2nd half.
Subs could/should have been done earlier. Pep isn't faultless. Still one of the very best managers though, not just now but in history.
We have just come of a break for covid, played Real over a week ago, training in the sun, 5 substitutes.
Go and get the result against Lyon then worry about the condition of the players, IF we had gone full tilt on Lyon with our strongest side the game could have been over at half time, then use the subs to rest players with Bayern in mind.
I agree with your assessment but it also paints a picture of total arrogance if true on Pep.
