Spain have named an alternative Euro 2020 squad that will train in a parallel bubble to the main team where there has been a Covid-19 outbreak.
On Sunday it was announced captain Sergio Busquets had returned a positive coronavirus test and soon after Leeds United defender Diego Llorente was also ruled out.
The outbreak prevented the original Spain squad from playing their scheduled friendly against Lithuania on Tuesday. Instead the Under-21 side, who recently reached the semi-finals of the European Championship, were called up in their place.
The weakened side performed excellently, strolling to a 4-0 victory thanks to goals from Hugo Guillamon, Brahim Diaz, Juan Miranda and Javi Puado.
Sergio Busquets tests positive for Covid-19 with Spain's Euro 2020 warm-up game against Lithuania set to be fulfilled by the Under-21 side.
Daniel James can use good performances for Wales at Euro 2020, like in their opener vs Switzerland, to prove himself to Man Utd boss Ole Gunnar Solskjaer.
Man Utd hope to open new contract talks with Paul Pogba after Euro 2020 to stop him leaving on a free transfer next summer.
Man Utd midfielder Donny van de Beek has withdrawn from the Netherlands squad with an injury and will miss Euro 2020 as a result.
Alongside six senior stand-by players - Kepa Arrizabalaga, Raul Albiol, Rodrigo Moreno, Carlos Soler, Brais Mendez and Pablo Fornals - they will form a 17-man parallel training bubble. Should the original squad be prevented from competing due to the coronavirus outbreak, this group would likely form La Roja's squad for the tournament.
If this does happen Spain would still stand a good chance of progressing. As well as several solid senior players, the young guns called up include Barcelona centre back Oscar Mingueza, Real Madrid's Brahim Diaz and Getafe wideman Marc Cucurella.
They kick off their Euro 2020 campaign against Sweden on Monday 14 June, before facing Poland and Slovakia in Group E.
