Europa League round-up: Barca turn on the style in Naples

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.

Thomas Delaney was sent off for a second booking in the 91st and Dinamo hemmed the Spaniards into their area for the six minutes of added time, even throwing their goalkeeper up to contest a late free kick.

Porto also had to scrap deep into
