Its not that easy mate, 99% of the strikers in the football world will not be good enough to play for Everton. We are in 7th place in arguable the first or second best league in the world. That means the pool of strikers available to us will not be great straight away. Then you have the fact that it is January and any centre forward good enough to play for us will be heavily involved in a team that is only half way through a season and either he will not want to leave, or the manager will not want the player to leave until the summer.
The argument that we had the summer to buy a striker I fully agree with, however the manager came in and decided to spend the summer assessing his squad. This meant he has been able to allow the youth that was capable of it to prosper(if most on here had their way we would have signed enough players in the summer that Holgate and Davies would still be names we hear about now and again in the reserves). On top of that, in them summer months assessing the squad he has quickly established which players are 'deadwood' and he has moved nearly all of them players on inside 6 months.
I understand the thirst for new players, and even more so a centre forward. But if you look at the bigger picture this manager has not put a foot wrong since he walked in the door bar maybe a dodgy goalkeeper signing and a run of 10 poor games when it was pretty obvious he was still working the players out and they were him. This man will not settle for second best, if we haven't signed a forward it is because he doesn't want any available to him.
