Athletic Bilbao came from behind to secure their place in the group stage of the Champions League with a 3-1 victory over Napoli.

But Athletic responded with three quickfire goals after the hour mark.
Aritz Arduiz bagged two of them, afforded plenty of time before firing in Markel Susaeta's 61st minute cross and then capitalising on a defensive mistake to put the ball beyond Rafael Cabral in the 69th minute.
Five minutes later, Ibai Gomez drilled in a third to see off the Italians.
Swansea City have completed the signing of Argentine defender Federico Fernandez from Napoli.

We will face a great team and the second leg will be in an incredible (San Mames) stadium. The (San Mames) crowd is like their 12th man.
Athletic's strongest weapon is the group, with players who have been together for many years and have the support of a city that never loses its passion.

Napoli coach Rafael Benitez has rubbished speculation that Jose Callejon could join Atletico Madrid this summer by insisting there is "no chance" the Italian club would sell the forward.
Primera Division champions Atletico were among the clubs reported to be chasing the 27-year-old, who enjoyed a stellar first season in Serie A last term and scored 20 goals in all competitions following a 10million euro (£8m) move from Real Madrid.
Reports that Callejon wanted to seek a return to the Spanish capital grew after Benitez removed the player from a training session on Sunday, but the former Chelsea and Liverpool boss has denied a rift between himself and his fellow Spaniard.

It was very simple, he was training without intensity, but there was no problem.
I wanted to bring him here, he scored 20 goals and I would have liked to have seen him called up to the Spanish team.
The coach hinted that Atletico had expressed interest in signing Callejon, but revealed Napoli had turned down their offers.
A team made us several large offers for him but we rejected them, we don't want to sell him and there is no chance we will.
Napoli forward Jose Callejon has revealed the club turned down a big money offer for his services from Spanish giants Atletico Madrid this summer - and is pleased they did.

My agent told me about it.
I was glad (the bid was rejected) because I really want to play in this shirt and have another four years on my contract. I feel good here, I feel the affection of the people.
In football, never say never, but with (Napoli boss Rafael) Benitez I have my freedom and I do not want to give it up.
