Vicente del Bosque believes new Real Madrid signing Isco is the "future" of Spanish football.The 21-year-old was unveiled as a Madrid player yesterday in front of 7,000 fans at the Bernabeu, and has signed a six-year deal with the club, after moving from Malaga for a reported £23 million fee.The midfielder was one of the stand-out performers in Spain's recent triumph at the European Under-21 Championship in Israel but has appeared just once for his country's first team, coming on as a substitute in a friendly against Uruguay in Qatar last February.Del Bosque has assured fans they can expect to see much more of Isco in the coming years."We have a lot of faith pinned upon him, he is the future of our national team," Del Bosque told Radio Nacional de Espana.Madrid are also reported to be interested in signing Isco's Under-21 team-mate Asier Illaramendi, and the Spain coach, who was in charge of Los Blancos between 2000 and 2003, gave his seal of approval to a potential move for the Real Sociedad man."Illarramendi is the complete midfielder. He has great ball distribution and he can get forward into the opposing box. He has the mentality to play for any team in the world," he said of a player whose performances were key to Sociedad finishing fourth in La Liga and qualifying for the Champions League play-offs last season.
