Napoli full-back Camilo Zuniga is reportedly free to join Barcelona this summer if the Spanish outfit bid £12m for his services.

The 28-year-old is widely regarded as one of the best attacking defenders in European football, with a number of clubs believed to be interested in his signature.

According to Mundo Deportivo, £24m has been the price quoted by Napoli, but Zuniga has a clause in his contract meaning that he can leave for £12m if Barcelona are the bidding club.

The same report claims that Napoli want to sign Alex Song and therefore a swap deal could also be negotiated between the two teams.
