It may not be the complete answer , but it might go a fucking long way to help, oh, and it's not one, it's two we need, and have done for three and a half seasons.
To stand any chance of progressing you need at least three good strikers, at the moment we have not really got any, assuming we don't look at Suarez as a striker per se.
If we have extra players up front it stops us playing every Tom Dick and Harry out of position as pretend forwards, it saves having four central midfielders in the team.
