We simply can't control games anymore in the same manner, and Pep's style of football requires little room for error in possession otherwise it leaves you completely exposed, just by the very nature of how high we get up the pitch.
As I said on a thread last week, the signs were there last season despite getting over the line, but there was a period last season where every goal we conceded were almost identical to each other, when we couldn't defend after a turnover of possession.
Until we get some new legs and players who can start controlling a game again, these results will be the norm.
