It's neither nonsense nor bollocks,
that's the over-egging if anything going on here - we haven't had another striker who did with the ball what he would pretty regularly do with the ball, that's the short and tall of it for me. It's fine and totally welcome if you want to argue against that personally-held position, but I've very specifically defined what it is I mean (and no, not that Suarez is "the best Liverpool player", I don't have him top of that list), and provided the obligatory youtube video with daft annoying soundtrack to boot.
It becomes pretty difficult when you're comparing players from other positions, because you're comparing different disciplines; Suarez didn't showcase such a complete mastery of passing or crossing because that often just wasn't his job, from where he was on the field. Gerrard evidently has him licked on receiving the ball in midfield and long-range attacking pinpoint passing from deep for instance, because Gerrard did absolutely shitloads of that and became very adept at that function in the side. From that point of view, you can say Barnes or Souness can't and shouldn't be judged properly alongside him at all, so you can't say he's technically 'better' than them (and I know of almost all the beautiful goals Barnes scored for us, I haven't once denigrated his ability with the ball). But I would absolutely contend that he has shown, for all to see right now, significantly better mastery of the ball than any of them when it comes to getting it in the back of the net frequently and as spectacularly and imaginatively as possible. Rush was his superior when it comes to just getting it there efficiently without fuss or a great deal of invention (he defo had his moments though), but who knows how many Suarez might end up with?
Souness being the silkiest hardman ever doesn't mean Suarez isn't more technically gifted; that hardman part is a qualification, that doesn't really matter when talking purely about (attacking) technique, which we were. That hardman with a silken touch angle is what made him a fucking brilliant effective player for us, but no one is going to argue he's one of the most technical midfielders ever, because some far less hard men were far more technically adept.
I shouldn't have to keep making the point that I'm not saying the others are lesser Liverpool players, just that Suarez has something on them from a purely technical standpoint. In fact, the South Americans have traditionally had something on us all - the very greatest and most audacious technique in football has been desplayed for the most part by Latin American players; Coutinho is rightly miles away from being considered a legend here, but his delicate caress of the ball is something to behold.
He may well turn out to be our greatest technical player, we'll see what else he conjures up, but forces of nature like Kenny, Ste and Luis have other stuff going for them which elevated them beyond such things.
I honestly don't see how you could say Suarez was better technically than say Fernando Torres. It wasn't Suarez technique that made him special in the slightest. It was his incredible imagination and ingenuity.
You can imagine doing something, but you still have to strike the ball the right way to make it reality, and that involves great technique. Megging is a technical skill, the variety of the goals he's scored demand great technical skill. You can fairly argue he's been inconsistent with it, but then so was Ronaldinho.
Like I say, he had/has many more things going on that make him 'special', but that application of imagination through technical quality is one of them.
