Matthias Sammer has hit out at the Spanish Football Federation (RFEF) after Javi Martinez was unable to feature for Bayern Munich on Saturday.
Die Roten had to make do without the 24-year-old midfielder as they edged to a 1-0 victory over Eintracht Frankfurt thanks to Mario Mandzukic's early strike.
Martinez did not travel with the squad, deemed unfit after flying back late from Spain's 2-0 win over Ecuador on Wednesday, and Sammer was highly critical of how the Spain camp treated the Bayern player.
"Javi came back in a state," 45-year-old German fumed. "I have absolutely no sympathy for the Spanish Association. This is an outrage for the player.
"These players are glad and happy to work for [their national team] but what is expected of them is an outrage. Javi was completely empty. Therefore, the coach did not take him [to Frankfurt]."
Sammer went on to call on national team federations to communicate better with clubs in order to avoid a repeat of the incident.
"Communication is a disaster," he continued. "Invitations to the internationals come too late and then we also learn quite late when our players come back. How can you deal with that?"
