Rodrigo Moreno, Pablo Fornals, Carlos Soler and Brais Mendez will join Spain's parallel bubble for training ahead of Euro 2020 after Sergio Busquets tested positive for coronavirus.

The Royal Spanish Football Federation (RFEF) revealed on Sunday that captain Busquets had contracted COVID-19 just eight days before Spain's first game of the European Championship against Sweden.

With the senior squad in isolation, Spain will be represented by the Under-21 team in a friendly against Lithuania on Tuesday.

The RFEF has now announced that Leeds United forward Moreno, West Ham midfielder Fornals, Valencia midfielder Soler and Celta Vigo midfielder Mendez will enter the bubble on Tuesday.

Another "small" group of players will also train with the senior squad after the game against Lithuania, with Spain's final Euro 2020 squad dependent on further coronavirus test results.

An RFEF statement said: "In anticipation of the possible consequences that Sergio Busquets' positive could bring, the coaching staff has decided to incorporate a group of footballers to complete training during the next few days under Luis Enrique's orders within a parallel bubble.

"In this sense, tomorrow [Tuesday] the players Rodrigo Moreno (Leeds United), Pablo Fornals (West Ham United), Carlos Soler (Valencia CF) and Brais Mendez (RC Celta) will join the sessions in Las Rozas.

"In addition, once the game against Lithuania is over, a small group of footballers yet to be confirmed will join the training sessions of the senior team under the same conditions as the previous ones.

"They will train at different times and will not mix in any case with the summoned.

"The players invited to the training sessions will remain outside the Ciudad del Futbol bubble and will go daily to Las Rozas after having passed the relevant daily tests before their arrival and during their stay.

"Their definitive incorporation to the Euro 2020 list will be evaluated based on the results obtained in the coming days."
