Football has it own pattern of play. What may work for a team may be a problem to another team. The defensive strategies was mostly used by Jose Mouriho and the pattern worked for him. Massive defense and massive attack. The strategy worked at then but not longer now as managers have been able to study the approach and come out with an answer.

The best defense strategy will depend on the depth of the squad you have at your disposal in sense that players can cover up for their team mate during set pieces. Back then best defense strategy was known as packing of buses but it was working then, at least we know that 1 goal can win a match.
