Goals from Ezequiel Lavezzi, David Luiz (OG) and Javier Pastore were enough to defeat Chelsea - whose performance deserved little more than the end result.
Of the Chelsea players only a few came out of the game with real recognition - one of whom would have to be Eden Hazard.
The Belgian dazzled at times, and although it was certainly not the best performance he put in all season, he was still excellent.
He tucked away his penalty in the first half with the usual aplomb and his left-foot volley was just inches away from being one of the best goals in the Champions League this season.
And one person in attendance was his little brother.
Thorgan Hazard, also a Chelsea starlet, is currently making waves on a loan spell at Zulte Waregem and the short trip across the border to check out his brother and future team-mates in action was no inconvenience - as he shared on his official Instagram account yesterday.
Hazard will hope that the next time he is at a Champions League game for Chelsea is playing for the club - and not watching from the stands.
