Real Madrid midfielder Toni Kroos is upset for Bastian Schweinsteiger over his knee injury.
The Manchester United midfielder had scans on a medial ligament injury suffered on his first training session back with his international team-mates and a timescale has yet to be decided on his comeback.
Kroos said: “His value for the team has been underlined and proven many times over.”
“I won’t beat about the bush, it’s really key for Bastian to be part of the team.”
“It’s not his first injury, either, so he’s got a certain expertise as far as coming back from injuries is concerned and even if he doesn’t make the first group match then he needs to at least be an intricate part of the squad.”
