Keeping a tight defence is always an important feature of a championship winning team, and it it is worth noting that the two leaders this week have recorded three clean sheets in a row. Luxemburgo appears to have found the formula at last to protect Casillas in the Real Madrid goal, and Javier Aguirre's rotation system at Osasuna is also bearing fruit, with Ricardo and Elía also sharing goalkeeping duties between them. Meanwhile last season's Zamora, Víctor Valdés, drops out of our chart this week as some slack defending by Barcelona allowed Deportivo back into the game. Generally though it was a low scoring weekend, with Casillas and Ricardo just two of eight "porteros" to keep clean sheets. The other six were Doblas (Betis), Armando (Cádiz), Prats (Mallorca), Aouate (Racing), Riesgo (Real Sociedad) and Palop (Sevilla). (17.10.05)
