THE Turks were underdogs for this tie and did well to secure a 3-2 first-leg victory at home.
But Sevilla's away goals could be crucial in deciding who goes through and they have proved their expertise in knockout tournaments by winning the UEFA Cup in the last two seasons.
An Edu own goal and Julien Escude's strike twice hauled the Spaniards level in Turkey after Mateja Kezman and Lugano had struck.
However, Semih Senturk's late winner will give Zico's side hope they can shut up shop in Spain and make the last eight.
ODDS TO WIN IT: Sevilla 18/1, Fenerbahce 80/1
