Here's a post I did earlier which will cover off the Liverpool connection.
As I've said subsequently, it wasn't that he managed Liverpool that was an issue for me, it was the things he said about us when he was their manager. Relationships between the two lots of fans where probably at their worst ebb during his stint at Anfield. A lot of that was fueled by his comments and attitude towards us whether you're prepared to acknowledge it or not.
You mention James in your post. James was a player I was a big fan of last season, and I've defended him a lot in these pages because many in here suddenly decided he was the antichrist or something. But I said throughout the window that he didn't fit in with Benitez style of play and that it would be probably best for all concerned if he left the club, provided he was replaced in the squad. The end of the window came and he was still here so I wanted him to get himself fit and and available for selection, acknowledging that he would be a bit part player, mainly from the bench when we needed something different. Our squad, from an attacking viewpoint, was terribly thin and I thought we couldn't conceivably sell him before the January window seeing as we couldn't replace him. But no, Benitez obviously didn't want him around the squad so we got rid, which left the squad incredibly short in attacking players, evidenced by us having to play Gordon away at United and having 2 teenagers as our only forward replacements in the bench. All because he put his longstanding personal dispute with the player ahead of the good of the club.
Anyway, bottom line here is that I should be able to say that I dislike somebody on an internet forum without having to apologise for it. or even explain myself.
