Sergio Busquets is back in the Spain squad after returning a negative coronavirus test.

The Barcelona midfielder had been isolating since testing positive for the virus on June 7, which prompted concern of a possible outbreak in the camp prior to the start of Euro 2020.

Coach Luis Enrique summoned players to train in a parallel bubble in case of further infections, but only Diego Llorente returned what was later suspected to be a false positive test.

On Friday, the Royal Spanish Football Federation (RFEF) said Busquets would be returning to the squad after testing negative for COVID-19 and travel with his team-mates for Saturday's match with Poland in Seville.

In Busquets' absence, Spain drew 0-0 with Sweden in their opening Euro 2020 Group E game, a match in which they had 85 per cent of the possession but only five shots on target.

They have won eight out of 10 previous matches against Poland, with their only defeat coming in a friendly in Barcelona in November 1980.

La Roja are looking to avoid consecutive scoreless performances for the first time since the 2013 Confederations Cup.
