Errrmm, no. The goals they conceded in the CL final were the midfield's fault because of they way they were scored - in each instance it was a midfielder making a mistake in either letting his man go, or failing to close down Kaka, Shevchenko or Seedorf.
When they didn't concede it was because they defended fantastically as a unit, but Carragher was head and shoulders above everyone else in that defence. You only had to watch the games to know that whilst Liverpool's defence clearly were very well-marshalled by Hyypia and were positionally excellent, Carragher was always the one making the most important last-ditch blocks, pinpoint tackles in the area and towering clearing headers - there's a difference between a good defence and having good defenders. Carragher was the best of Liverpool's defensive unit - an outstanding unit in itself, which on one occasion, in the first half of the CL final, was let down by the midfield being unsure of their duties. In the second half of the final, the defence were once again outstanding - but then again, you probably didn't watch that.
