Wenger with Jeffers.
Ferguson with quite a few recently.

Even Shanks and Paisley bought the odd cr*p one.
There is no guarantee when it comes to the transfer market, you pays your money and takes your chances. I would say that Rafas done Ok but not exceptional up to now in the transfer market .
Alonso and Sissoko without doubt the pick of his buys.(some would include Reina and I wouldnt argue)
Morientes,Nunez,Pelligrino and Josamy the worst (but who could have guessed Morientes would fail?)
Garcia, Reina, Crouch and Carson good buys but the jury is still out as to how good ,and for the rest only time will tell(but Gonzales looks good)
But now its crunch time. The sale of Morientes and impending sale of Cisse means Liverpool need strikers and unfortunately our recent record for buying good prolific strikers is awful. Morientes, Cisse,Diouf and Heskey cost Liverpool over £40million, near enough £1million per goal (not a great return) This puts additional pressure on Rafa to get it right, especially as Chelsea, United,Newcastle,and Spurs are all after strikers as well.
If Rafa gets it right it could be the finishing piece in the EPL jigsaw and maybe, just maybe we could be champs. If Rafa gets it badly wrong we may have missed our chance and it could be a long road back.
The players that we are supposedly interested in haven't exactly inspired me but hopefully its just paper talk. I personally dont want Bellamy,Viduka,Johnson or D'viao. I am unsure about Kuyt and Defoe and apart from Owen (who may or may not be one solution) and Tevez (too dear) I have no other suggestion than trust in Rafa.
