Lille caused the upset of the round with a thumping 3-0 away win against Milan, a result that ended the Rossoneri 24-game unbeaten streak.
Attacking midfielder Yusuf Yazici netted a hat-trick, his second of the campaign in this competition, to stun a silent San Siro and the Ligue 1 side have now overtaken Milan as the group's top dogs.
Meanwhile, another treble was scored in Group H, as Sparta Prague's Lukas Julis destroyed Celtic in a 4-1 win at Celtic Park. It was the first hat-trick scored by an opposing player at the ground for nearly 40 years.
Elsewhere, Leicester City's Kelechi Iheanacho performed brilliantly as the Premier League outfit completed a comprehensive 4-0 win against Braga. Brendan Rogers' side are now a perfect three from three so far in Group G.
Napoli's Diego Demme was the standout performer for the Partenopei as they fought from a goal down against Croatian side Rijeka. Demme scored the equaliser in the first half before the Italian side completed their comeback in the second half.
Bayer Leverkusen's Leon Bailey was also amongst one of the highest performers of the round. The USA international scored twice in the German side's 4-2 away win against Hapoel Beer Sheva and looks to be finding his form once again after a difficult period in and out of the side.
