Barcelona defender Dani Alves has agreed to two-year contract extension to the end of the 2016-17 season with an option for a further year, the Spanish and European champions said on Tuesday.

Alves, a Brazil international, joined Barca from Sevilla in 2008 and has played a key role in a golden period for the Catalan club, winning 19 trophies including three Champions Leagues, five La Liga titles and three King's Cups.

The 32-year-old has made 343 appearances, more than any other non-Spaniard, and is one of seven players who won a treble of Europe's elite club competition and the domestic league and Cup in both 2008-09 and again in 2014-15.

One of the most popular members of the squad and a close friend of Argentina forward Lionel Messi, Alves will face stiff competition for his place at right back after Barca signed Aleix Vidal from Sevilla on Sunday.

Spain international Vidal will, however, be unable to play until January as Barca have been banned by FIFA from the transfer market until then over irregularities in the signing of foreign under-18 players.
