Despite some minor deterioration in Petke's recent play he is still a solid central defender. Jolley has been excellent and Ziade reasonably dependable. Chronopolous is somewhat weak on the left (too bad Perez wasn't appreciated). But all this pales in comparison to the the defensive problems of the midfield. Let me state it simply. We cannot afford defensively to have two of any of the following players on the field at the same time. Really confirmed after watching last night's Columbus game. Lisi Alvarez Paule Davis Whatever else they bring to the table they simply lack the speed, athleticism and heart, (Paule excepted as to heart) to regularly win balls and shut down the oppositon before the reach the final third. We may be able get by with one of either Paule or Davis in mid but not both. As to Lisi and Alverez, waive em now and spare us the pain. I'd rather see us pick up some A-League mids with speed, athleticism, heart and just a modicum of skill to join Williams and Moore in the midfield.
