The first UEFA Europa League group games did not disappoint thanks to Zenit's incredible comeback, the competition's fastest ever goal and surprise wins for Feyenoord and Hapoel Beer-Sheva.
Manchester United, many people's favourites to lift the trophy in Stockholm in May, began with a loss at Feyenoord but were not the only high-profile club to stumble, Inter humbled 2-0 at home by UEFA group stage debutants Beer-Sheva.
Zenit – three down with 14 minutes left – looked certain to become another major casualty but somehow snatched victory from the jaws of defeat against Maccabi.
Beer-Sheva's fellow first-timers Zorya had to settle for a draw with Fenerbahçe, who equalised in added time, while Dundalk – even with ten men – came from behind to hold AZ and Sassuolo beat Athletic.
Elsewhere, Osmanlıspor coach Mustafa ReÅŸit Akçay made it 19 UEFA club competition games without defeat courtesy of a 2-0 triumph over Steaua.
