Under Lippi, in Zidane's first season, we had something like 5 lines. 3 defenders in one line, Deschamps in the second line, Di Livio and Pessotto in the third line (these two running up and down), Jugovic and Zidane in the 4th line and Del Piero-Vieri in the 5th line.
But these guys ran like they were doped. It was unbelievable how much space all of them covered, especially the wingbacks and Jugovic.
