This. The main reason our attacking players look worse than they actually are, is because of our extremely slow tempo, we play football at a crawling rate; our fairly predictable playing style and poor attacking movement lacking cohesion.
The secret to the likes of City, Liverpool scoring many goals and looking fluid is mainly because of their direct as hell attack, aggressive pressing, using overloads from the wings or midfield and their superb movement. More than the players, and I might receive flak for this comment, I strongly believe it is mainly due to the tactics and coaching of our manager. And I don't believe buying Player X or Y will have a dramatic effect in our play.
