Barcelona hit top gear to trounce Napoli 4-2 away from home and sail into the last 16 of the Europa League 5-3 on aggregate.
Jordi Alba gave Barça the lead in the eighth minute of the knockout stage play-off second leg with a rare strike on his weaker right foot and Frenkie de Jong put the Catalans further ahead with a curling shot after being teed up by a sumptuous backheel from Ferran Torres.
A Lorenzo Insigne penalty gave Napoli hope but Gerard Pique restored the Spanish’s two-goal advantage right before half-time.
In-form Pierre-Emerick Aubameyang added a fourth in the second period, scoring for the fourth time in two games after hitting a hat-trick at Valencia in La Liga on Sunday. Matteo Politano reduced the deficit to two goals in the 87th.
