Already qualified: PAOK FC, R. Standard de Liège*, Hannover 96, PSV Eindhoven*, Legia Warszawa, Sporting Clube de Portugal*, Stoke City FC, Athletic Club*, FC Metalist Kharkiv*, SC Braga, Club Atlético de Madrid, FC Schalke 04*, FC Twente*, RSC Anderlecht*, FC Lokomotiv Moskva, S.S. Lazio, Beşiktaş JK*, FC Steaua Bucureşti, FC Salzburg, Wisła Kraków
• PAOK have clinched qualification and Rovers are out.
• Rubin, in second, are three points above Tottenham. To qualify Spurs must win in Dublin, hope Rubin lose, and make up a goal difference deficit which currently stands at five. If the two teams finish exactly level on goal difference and goals scored, Tottenham will qualify due to their higher coefficient.
• A Rubin win would leave them first above PAOK.
• The group is decided with Standard finishing top and Hannover second.
• The group is decided with PSV finishing top and Legia second.
• Metalist have clinched the group and Malmö are out.
• AZ, in second, are two points ahead of Austria and would be through with a win.
• Austria must win and hope AZ lose, or if Alkmaar draw the Vienna side need to overhaul a goal difference deficit of six. If they finish level on goal difference and goals scored, AZ have the higher coefficient.
• Brugge and Braga are both three points ahead of Birmingham. Braga are through as they have a superior head-to-head over Birmingham.
• Birmingham can overtake Brugge with a victory against eliminated Maribor should the Belgian side lose as the English side have the superior head-to-head record.
• Club Brugge won at Braga on matchday two so a draw in the return would take them through as group winners.
• Atlético have qualified and a draw with eliminated Rennes would clinch first place.
• Udinese are three points ahead of Celtic, who would go through on head-to-head record with victory in Italy.
• If Udinese draw they will finish second and will finish top with a win if Atlético lose.
