Two goals in the space of five minutes for the already-qualified Yellow Submarines, courtesy of Gerard Moreno and Luciano Dario Vietto, were enough to secure the victory.
Meanwhile, Borussia Monchengladbach secured first place in the group with a thumping 3-0 victory against FC Zurich, with Patrick Herrmann's strike and Branimir Hrgota's brace helping the German outfit pip Villarreal to the top of the table.
The Belgian outfit nicked a 2-1 against HJK, with Lior Rafaelov netting in the 88th minute, while nine-man Copenhagen took the lead, only to then be pegged back before seeing Mikael Antonsson and Mathias Joergensen sent off. It was all one-way traffic thereafter, with the visitors scoring four more goals to secure a 5-1 victory.
Besiktas pipped Tottenham Hotspur to first place in Group C after the Turkish hosts secured a 1-0 win against Mauricio Pochettino's charges, while already-eliminated Asteras Tripolis and Partizan played out a goalless draw.
Dinamo Moscow had won Group E before tonight's 1-0 win away to PSV, who had guaranteed second spot before kickoff. Aleksei Ionov scored the 90th-minute winner. Meanwhile, Panathinaikos and Estoril, both already eliminated, drew 1-1.
Finally, Group F saw Dnipro Dnipropetrovsk seal qualification with a 1-0 win at Saint-Etienne, pipping Qarabag FK to second place after the Kazakh outfit could only draw 0-0 with already-qualified Inter Milan.
