La Roja's preparations for the tournament were hit by Sergio
Busquets' positive coronavirus test on Sunday, with the entire team forced into
isolation.
Tuesday's friendly against Lithuania also had to be
re-arranged, with the Royal Spanish Football Federation (RFEF) promoting their
entire Under-21s side, though La Rojita took their opportunity to impress.
Hugo Guillamon, Brahim Diaz, Juan Miranda and Javi Puado
scored in a 4-0 win, but it was confirmed after the match that another member
of the senior squad – Leeds United centre-back Diego Llorente – had tested
positive for COVID-19.
Luis Enrique had already created a parallel training bubble
with standby players, including Rodrigo Moreno, Pablo Fornals, Carlos Soler,
Brais Mendez, Raul Albiol and Kepa Arrizabalaga.
With Spain starting their campaign against Sweden on Monday,
11 of the players who played against Lithuania have now been added to the
separate training bubble.
Alvaro Fernandez, Oscar Mingueza, Marc Cucurella, Miranda,
Gonzalo Villar, Alejandro Pozo, Diaz, Martin Zubimendi, Yeremy Pino, Puado and
Bryan Gil – the only player to feature on Tuesday having represented the senior
side in the past – are the youngsters selected by Luis Enrique, who only named
24 players in his initial squad.
