You need to discern between comments and criticism. We would all buy different players at varying prices, use formations and tactics that are at odds with the next person. That is fine. It is individuals expressing an opinion about a team they support. Should there be players that the media or members of this forum, think are a must, and I think are not, that is perfectly acceptable. After all, it is not people being critical of the Club or their supporters, just a different way of doing it. At the right price I would sign Stones and Sanchez, others may disagree with me. That is not them being very negative in their posts, they just happen to have a different opinion and may well be right.
We are not in the days of Custers Last Stand, we can take opinions of those alongside that may be disagreeable to us, and take it in our stride.
