Chelsea duo Marcos Alonso and Alvaro Morata have been included in Luis Enrique's first Spain squad, with only two Barcelona players, Sergi Roberto and Sergio Busquets, in the 23-man selection.
Spain begin a new era under the former Barcelona coach with a Nations League game against England on Sept. 8 before hosting Croatia at Elche on Sept. 11.
Real Madrid have six players in the squad -- Dani Carvajal, Nacho, Isco, Dani Ceballos, Marco Asensio and Sergio Ramos -- but summer signing Alvaro Odriozola misses out.
Barcelona left-back Jordi Alba, Atletico Madrid midfielder Koke and Celta Vigo striker Iago Aspas are absent.
