Zidanesbestmate - Are you saying that you are personally acquianted with ZZ? Are you also saying that you have a similar relationship with Houllier. Whilst I do share your enthusiasm for a move for ZZ to Liverpool, and also share knowledge that there have been serious talks, there has still been no agreement unless the two have privately agreed. If you are 100% about this it must be because you know them otherwise you can't possibly know, and if you do know him ask him if he'll still play for us if we are not in the Champions League.
But realistically even though I know what is going on I can't see ZZ joining us unless ZZ and H really do have a strong relationship (and you don't need to tell me they do because I know, but is it that strong?). For the money being talked about (which is a lot more than 15) we could buy three highly rated midfielders. This to me sounds a better option. ZZ is a great player, don't misunderstand me, but I don't think he would necessarily be a good buy for LFC. We have talented youngsters coming through, the players in the team love our club and we are going to be the gretest team in Europe within five years even without ZZ. So do we really need him? Personally I think buying the other three players would be a better option, but I ain't in charge and I do have faith in H., so lets wait and see.
