Upper hand to Porto after Jackson Martinez’s strike.
Rafael Benitez’s hopes of winning the Europa League for a second consecutive season are in the balance after his Napoli side lost 1-0 to Porto in their last-16 first leg.
Benitez, who won the trophy with Chelsea last year and also lifted the UEFA Cup with Valencia in 2004, will hope Napoli can overturn the deficit in next week’s return after a Jackson Martinez strike gave Porto the upper hand.
The Colombian striker, linked with a move to Naples last summer, volleyed low into the net in the 57th minute at the Estadio do Dragao after the visitors had failed to clear a corner.
