Swansea midfielder Leon Britton has warned Napoli that the tie is far from over ahead of their Europa League second-leg on Thursday.
The sides drew 0-0 at Liberty Stadium last week, making the Azzurri marginal favourites to progress but the 31-year-old says belief is high in South Wales.
“We are pleased that we didn’t concede at home,” Britton told the BBC.
“The advantage we have now is that even one goal in Naples could take us through to the next round.
“We believe we can get through to the last sixteen of the Europa League.”
