Yes the defence did really well last year. But no I would not describe Pope as a "brilliant" goalkeeper during that period. He played his part without too many silly mistakes. But lets look at the other side of the statistics. We let in the same amount of goals as City, but they scored over 20 more. That has to be our direction of travel and for that we would need a keeper who can anticipate, clean up and start meaningful passages of attacking play. Rather than hoof the ball into the stands (at best).
I think a big problem with our club for years is as soon as we get a decent player on the books, especially if they are a badge kisser, they become "brilliant" and immune from criticism. Remember when KK sold David Kelly, and later Andy Cole?
if we want to win stuff (I do) most of our current players will need to be upgraded imho
