A number of players currently on national team duty at the European Championship will also be required to serve their country at the summer games
Pedri, Eric Garcia and Pau Torres are among a whole host of Spain's Euro 2020 players to have been named in the Tokyo Olympics squad.
Luis de la Fuente named his final 22-man squad for the summer games on Monday, including a number of players currently starring at the European Championship.
Those who have been selected to play will only have a 10-day turnaround period between the Euros and the Olympics if Luis Enrique's side make it all the way through to the final at Wembley on July 11.
