It could be winner takes all on matchday five as Zürich and Villarreal meet in Group L, with the result potentially deciding both sides' UEFA Europa League destiny.
• Villarreal go through with a victory provided Steaua do not win against Osmanlıspor; Zurich qualify if they win by a two-goal margin or 1-0 and Steaua do not prevail.
• Zürich led within two minutes of kick-off when these teams met for the third time on matchday one, but the Yellow Submarine rallied to win 2-1.
• The clubs previously met in two high-scoring games in the UEFA Europa League group stage in 2014/15; Marcelino's Villarreal triumphed 4-1 at home but went down 3-2 to Urs Meier's side back in Switzerland.
• Current Zürich players Oliver Buff and Marco Schönbachler (with his only UEFA club competition goal to date) were on target in those matches, along with Villarreal's Bruno Soriano.
• Zürich are unbeaten in three games since that matchday one loss at Villarreal (W1 D2) and have not lost in their last seven group stage home games (W4 D3).
• Villarreal have drawn both of their Group L away fixtures, and are without a win in four European matches on the road (D2 L2).
• Zürich have failed to make it through the UEFA Cup/UEFA Europa League group stage in two attempts since making the cut in their first appearance in 2007/08.
• The Yellow Submarine have qualified for the round of 32 in all six of their previous UEFA Cup and UEFA Europa League group stage ventures.
