Not that I agree with the original statement but, just because we happen to be the highest scorers in the league doesn't mean we're clinical enough and that'll have to improve - 26 Shots for a return of 2 goals in our last match, that simply isn't going to cut it against Liverpool.
There hasn't been a game this season where we've been extremely clinical, but, It can be argued that we haven't needed to be on the whole considering the amount of chances we create over the 90 minutes.
We won't be afforded such luxuries against Liverpool and will need to be clinical, not that it should be a problem with our front line mind you.
