The replay was indeed an awful game. However, I also watched the first game which was much better - quite open and even with both sides playing some good football. Also, I watched Notts Forest completely outclass West Ham only to be comfortably beaten by Sheffield in the next round. They're clearly a better team than their league position suggests and are quite capable of pushing City very hard.
However, I have been impressed by the way City have played in the cup - possible banana skins avoided with sure footed performances at 'Boro, Southend and Brighton; comfortable home wins against Brighton and Sunderland without any fuss. Steve Bruce won't let them take the Blades lightly and City should be clear favourites to make the final. Fingers crossed!
