The match took place on Wednesday and ended with a 2-0 victory for USG, thanks to a standout goal from Youssef Hamoutahar, followed by a goal from Sekou Keita that sealed the win for the home team.
This is the second defeat for Newcastle in the UYL, following their loss to Barcelona in the first round.
