Ernesto Valverde wary of Napoli threat

Athletic Bilbao manager Ernesto Valverde has said that his team must be wary of Napoli's attacking threat in their Champions League playoff on Wednesday.

Last week's first leg in Naples ended in a 1-1 draw and Valverde believes that the experience will prove crucial to his players as they aim to reach the group stages of the tournament.

"Tomorrow's match is a final because one of us will be eliminated," UEFA.com quotes him as saying.

"But today we're better than in the first leg against Napoli as we had a few players who were playing in the Champions League for the first time, so some will at least have that experience now. We are aware of Napoli's potential, we are aware of what they have up front."

Bilbao suffered a 1-0 defeat against Malaga in their first La Liga match of the season at the weekend.
