Manchester United's David De Gea was on Tuesday handed a maiden call-up to the Spain squad for friendlies against Serbia and South Korea which precede Euro 2012.

De Gea impressed for the Under-21s as they claimed the continental crown in their age-group last year but he has never before earned inclusion to the full squad.

Atletico Madrid's Juanfran and Adrian Lopez were also called up for the first time, as were Malaga playmaker Isco, Benfica's Javi Garcia and Real Betis' Benat Etxebarria.

Del Bosque's 21-man squad does not include any Barcelona or Athletic Bilbao players as they meet in the Copa del Rey final on May 25. Chelsea's Fernando Torres and Juan Mata are also absent due to their participation in the Champions League final this weekend.

The final 23-man squad to travel to Poland and Ukraine will be named on May 27.

The Spain squad to face Serbia and South Korea is: Casillas (Real Madrid), Reina (Liverpool), De Gea (Man United); Arbeloa (Real Madrid), Ramos (Real Madrid), Albiol (Real Madrid), Alba (Valencia), Monreal (Malaga), Torres (Atlético Madrid); Domínguez (Atlético Madrid); Alonso (Real Madrid), Cazorla (Malaga), Etxebarria (Real Betis), Isco (Malaga), Garcia (Benfica), Soriano (Villarreal) Silva (Man City), Navas (Sevilla); Negredo (Sevilla), Soldado (Valencia); Lopez (Atlético).
