Bayern Munich boss Matthias Sammer has slammed the Royal Spanish Football Federation (RFEF) after the European champions' stars Thiago Alcantara and Javi Martinez returned exhausted from international duty with Spain.
Martinez played the full 90 minutes, while Thiago came on at half-time, of Spain's 2-0 friendly win away to Ecuador in Guayaquil last Wednesday.
Bayern had 15 of their 26-man squad away on international duty, but Sammer says the Spain pair were returned to the Bavarian giants in a tired state.
They arrived in Munich late on Thursday night after a long flight from South America ahead of the defending German champions' 1-0 win at Eintracht Frankfurt on Saturday.
Martinez was completely left out of the match squad for Bayern's below-par Bundesliga win while Thiago came on for just the last 25 minutes.
A furious Sammer said Bayern coach Pep Guardiola had no choice other than to leave out the exhausted Martinez.
"Javi came back in a state - I just don't understand what the Spanish FA are trying to do," Sammer, Bayern's director of sport, told German daily Bild.
"It is an outrage for the players.
"They go off only too happy to play for their country, but what is then expected of them is outrageous.
"Javi came back to us completely drained, which is why he was left out by the coach."
Sammer was particularly upset by what he claims is a lack of communication from the RFEF and Spain coach Vicente del Bosque.
"The communication was a disaster," fumed Sammer.
"The invitations to play came incredibly late and then we also learnt quite late when our players would come back.
"That is no way to deal with each other!"
