Barcelona found its scoring touch again to reach the round of 16 of the Europa League with a 4-2 win over Napoli on Thursday, while Rangers knocked out Borussia Dortmund in Glasgow. Frenkie de Jong scored with a long-range curler and newly signed striker Pierre-Emerick Aubameyang netted again for Barcelona, which had been held 1-1 at home in the first leg. The Spanish giant has struggled badly in its first season since the departure of Lionel Messi and was demoted to the Europa League after failing to advance to the Champions League knockout stages for the firs time since 2004.
