The Bayern Munich midfielder was forced to sit out his side's 1-0 win over Frankfurt on Saturday and the club's sporting director has slammed the RFEF.
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," Sammer said. "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," Sammer said. "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?"
