Bartra twice pulls Betis level before Parrott wins it against 10-man Lille

Bartra's first cancelled out Lille's opener. Alexsandro restored the home advantage three minutes later. Bartra levelled again four minutes into the second half, and Troy Parrott put Betis in front for the first time in the 54th.

Two goals from a centre-back in a European away tie is unusual. Doing it twice from behind, either side of the interval, kept Betis in a match they had spent the opening half hour chasing.

The red card

Lille's evening deteriorated further when Ethan Mbappé was sent off for an elbow to the face of an opponent.

Playing a substantial portion of a home European tie with ten men, having led twice, is the kind of collapse that tends to define a group campaign rather than a single night.

Around the round

The matchday was generous to attackers throughout. Paris Saint-Germain scored six against Slovan Bratislava. Barcelona scored five against Feyenoord. Borussia Dortmund and Villarreal produced five between them, including an added-time own goal from Dortmund's own two-goal scorer.

AEK Athens beat the Austrian side LASK 1-0 in Greece through a curling free-kick from the Romanian midfielder Razvan Marin midway through the first half.

Against that backdrop, Arsenal's 1-0 at Napoli and Manchester City's 2-0 at Porto looked positively restrained.
