In case you are purchasing tickets that say "TESSERA DEL TIFOSO: NECESSARIA" (SUPPORTERS CARD: NECESSARY"), you need to obtain the corresponding Italian supporters card in your own club or in a Lottomatica sales point. But, if you want to purchase a ticket for the away fans sections (settore ospiti) you must have the Tessera del Tifoso of the away team.
