This latest development comes as a major blow for Zinedine Zidane's men, who are hot on the tails of city rivals Atleti in the La Liga title race.

With their Champions League season over following their defeat to Chelsea in the semi-finals, Real Madrid have thrown all their efforts into trying to win this year's La Liga title.

Los Blancos find themselves two points behind current leaders Atletico Madrid with just two games remaining. Barcelona, meanwhile, are also two points back, meaning that things will get pretty interesting in the final two matchdays as all three teams battle it out for the coveted prize.

However, Zinedine Zidane has unfortunately been dealt a major blow ahead of his team's trip to face Atletico Bilbao this Sunday. Key midfielder Toni Kroos has been ruled out after coming into contact with an individual who tested positive for COVID-19. Although a statement from Real Madrid has noted that the World Cup and multi-Champions League winner has been tested, and all his results have come back negative, he still needs to remain in isolation.

Sergio Ramos, Dani Carvajal, Lucas Vazquez and Ferland Mendy are already out for the upcoming trip to take on the Basque outfit this weekend, and this is a game that Los Blancos must hopefully win in order to remain viable in the title race.

Real Madrid will then welcome Villarreal next Sunday, May 23rd. And naturally, the team's legions of fans will hope that Kroos continues to test negative so as to be able to be back in action for that must-win match.
