Real Madrid will be without midfielder Toni Kroos at least one month. The midfielder picked up a sports hernia this week and will have to spend a minimum of four weeks recovering from this injury, so Kroos won't be able to help the squad in the first few games of the season.
The pubalgia is always a very tricky injury and Kroos will need to take a cautious approach so that this problem doesn't compromise the rest of the season for him.
Without Kroos, coach Carlo Ancelotti will have to find a reliable midfielder to play alongside Casemiro and Modric, who are expected to be undisputed starters when the season kicks off. Valverde, Odegaard and Isco will likely compete for that third spot in the midfield until Kroos is back, all three of them trying to make a case for more relevant minutes this season.
Other key players like Benzema, Carvajal or Mendy haven't trained with the squad this preseason just yet, so it looks like Carlo Ancelotti will be forced to trust some of his reserves during the first few games of the season.
