Before this game I looked at his stats in the PL games in the last 6-7 games, and I think he shot at least 4 times in all of them except maybe two games.
In a 6-0 romp you would think that he would keep up those shooting numbers, but no, clearly with better attackers around him he no longer has the pressure on him to score. Pops up with an assist for Can and a key pass for Clyne's goal instead.
I've been puzzled over the Suarez comparisons, but watching some of his compilations - even from this season, you can really see it. Never say die tenacity is one part of it, but I think the other key part is he tries a lot of crazy tricks/dribbles, some of which don't come off, but which make him an unpredictable prospect to deal with for defenders. I think with Sturridge, Coutinho and Origi back, we're gong to see him show his value even more, as defenders have to deal with multiple goal threats from around the pitch.
