Coach Luis Enrique held a press conference after European champions Barcelona trained on Tuesday in preparation for their USA pre-season tour starting next week. The first match will be against the L.A. Galaxy at the Rose Bowl in Los Angeles, California. Among the players taking part in the training session were the newly acquired Arda Turan along with Luis Suarez, Adriano, Thomas Vermaelen, Jeremy Mathieu and Andres Iniesta. The rest of the players will arrive during the next few days, including the South American players who played in the Copa America: Lionel Messi, Javier Mascherano, Neymar, Dani Alves and Claudio Bravo. Last season Barcelona became the first team to complete a sweep of the Champions League and the two main Spanish domestic competitions in the same season on two separate occasions. Barcelona, who have now won Europe's top-tier competition four times in the past decade, first achieved the rare feat in 2009.
