One of the most important things he'll provide is the ability to break quickly from the front. He's awesome at anticipating quick sequences or counters, playing directly into attacking channels, and capitalizing on disrupted defenses before they have a chance to recover. His touches and passes in tight spaces are also being highlighted here, the kind of thing that was less common at Liverpool.
He showed it against Madrid in a match where our control was minimal and Espanyol today, he's a difference maker. Our system may be faulty in some aspects but Suarez's inclusion gives us the capacity to overcome that when things get tough. His individual abilities and tendencies can prove decisive even if we don't control a match or have the advantage.
