Sevilla should take the blame for the dire treatment of fans at last week's Europa League final, according to Frankfurt security chief Philipp Reschke.
Some travelling Rangers and Eintracht fans were left without water at the Ramon Sanchez-Pizjuan stadium despite the searing Seville heat.
The Ibrox club also complained about "over-zealous" search procedures at that saw battery packs and ear pods stripped from fans at the turnstiles.
