The first day's matches concluded!

Inter started well in group F, beating Real Sociedad without too much trouble with a goal in each half and only conceding the Spaniards' goal in injury time with the result now secure. The Turks of Fenerbahce rule with a clear 2:0 (double from Dzeko) Brentford.

In group G, Shaktar overwhelms the Italians of Empoli with a peremptory 4:0, while in the other match of the group, the show is lacking and between Arsenal and Flamengo, the fear of losing generates a disappointing 0:0.
