Had a look on a Norwich message board and the comments on Idah were very negative. Hard to judge what to make of that though as the comments about everyone were very negative.
Edit - it seems the fewest goals ever scored in an English league season (as in, not non-league) is 18, going back to 1899/1900. Norwich have 8 in half a season. Wow.
Norwich had two keepers and an U23 player on the bench but still couldn't fill it. But Palace were missing two of their best players in Zaha and Gallagher
