I disagree on Suarez , I think he's definitely better at Barcelona, mainly because he has Messi and Neymar flanking him rather than Sterling and Sturridge. Suarez assists and goals at Barca are off the charts. Messi is in a slight decline but that's cause he's now sharing the goals and assists around.
You'd be wrong then
Seriously though, I've had this discussion a few times on here. This is not a rose tinted view. I'm not talking about stats and I know he's receiving much more acclaim worldwide now, but somehow he was just more explosive when he was with us. Perhaps due to freedom that Rodgers afforded him or even because he was the player everyone looked to in that side. He's still brilliant at Barca and perhaps more clinical than ever, but I do feel he's had to curb part of his wildness to fit into that frontline and the club's philosophy. In 13/14 he had that rare quality you see in few players that allowed him to not only create moments of absolutely mind-bending sublime all by himself, but to lift everyone around him to extraordinary levels as well.
Of course he's got better players around him now. But I would take the animalistic wild Suarez of Liverpool over this one all day. It's not a huge difference, but it's enough for me. Stats-wise it's also important to bear in mind that the Spanish league is extremely poor beyond the top 5-6 teams. It's massacre for goals and assists down there.
