[Q]: Question: Is the captain of the 2007-08 FC Barcelona team still playing professionally? Passage:Most of the players have contracts beyond this end of season, but Deco, an important player, has his contract ending in 2008. The captain is still Carles Puyol, who is from Barcelona's youth system, plays in the first squad since 1999 and currently is the player with the most appearances (268). Currently, the highest scorer is Ronaldinho, with 80 goals. Also Ronaldinho, from August of this year, has a European passport. On mid-October, Samuel Eto'o received Spanish nationality, making him an EU player. The only non-EU player is Yaya Touré. Because Spain ratified the Cotonou Agreement in 2007, however, Touré is now considered an EU player, as his native country of Ivory Coast is a signatory to that agreement, and the 2003 Kolpak ruling extended the Bosman ruling to nations with an associate trading relationship with the EU.
