The 1991–92 UEFA Cup was the 21st season of Europe's then-tertiary club football tournament organised by UEFA. It was won by Dutch club Ajax on away goals over Torino of Italy. The victory made Ajax only the second team – after Torino's city rivals Juventus – to have won all three major European trophies (&lt;a href="UEFA%20Champions%20League"&gt;European Cup/UEFA Champions League&lt;/a&gt;, UEFA Cup/UEFA Europa League, and the Cup Winners' Cup).
