People harping on about Mancini would have done this or that are forgetting the "lack of ideas, no plan B" was a weekly gripe for many it was far worse of a problem back then against the top teams... Pep changes things all the time, he's got loads of ideas if you don't see that you know nothing John Snow.
He does however play high risk attacking football than can leave us exposed and left to defend "large spaces" as Pep puts it, which sometimes means our hole half with 3 defenders against 3. If we score our chances early no team keeps pressing high at 3-0 down and we pass them to a standstill if they try because we don't need to score at that point, we are also better in the second half once a game is safe(2-0 is never safe as they say) as the oppositions legs are normally done in the last 30 mins.
No manager gets every call right, no system is perfect, not every playercan be on form or 100% fit when you need them most... I still wouldn't swap our football for defensive Italian style or Mourinho style. It wasn't "our year" this year as them scousers say.
