Alba is a good footballer and certainly better on the ball than Robertson. Coutinho is more than technically "okay", he was one of the best players in the world at what he does when he was at Liverpool. It's not worked out for him so far at Barcelona, but that talent hasn't just disappeared. I wouldn't call Suarez average either, he is capable of doing incredible things with the ball. I think Suarez's problems are physical, not technical, he looks heavy and slow compared to when he was in England. And again, Rakitic is not average, he is technically better than every Liverpool midfielder except Fabinho.
Look, we could sit here and debate each individual player for hours, but let's think about it this way: are these players technically (forget physically, psychologically or tactically) better than their Liverpool counterparts? Of course they are. There's no way I can be convinced that Milner is better on the ball than Rakitic, or Origi than Suarez, or Robertson than Alba, or Shaqiri than Coutinho.
What those Liverpool lads have, though, is supreme fitness, a tremendous work ethic, and belief in themselves as a team that they can beat anyone. Barcelona don't have any of that, and as a result they got ran into the ground by a very fit and intense Liverpool side. They turned up at Anfield looking like they thought they could just walk around and wait for Messi to score. You can't go into games like that at the top level. It might be enough against Leganes or Levante but against Liverpool and even Roma, you need to work hard and fight for everything.
