Barcelona hit top gear to trounce Napoli 4-2 away from home on Thursday and sail into the last 16 of the Europa League 5-3 on aggregate.
Jordi Alba gave Barca the lead in the eighth minute of the knockout stage playoff 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.
