What a silly question.
We have the best defence in England and one of the best defences in Europe.
Does that mean I think we would stop Bayern, Real or Barca from scoring against us? No, I think they would all score several goals against us, because we play attacking football and defend through counter pressing. Counter pressing which is susceptible to transitions which teams like Bayern have exceptional quality to thrive in.
If we played low block football against these teams then I would expect us to concede very few because we're also excellent at low block defending which is much harder to penetrate like City found out, but we were never going to do that at home, perhaps rightly so, but they then exposed the space we left.
If we played Real in the semi, and we pressed high and squeezed up, I'd expect Vini and co. to score a truckload like they've done against City. If we parked the bus and played on the counter, I'd favour us to concede fewer.
