Mark Hughes wants greater respect from club managers who have wrecked his squad to face Hungary tonight.
Hughes is angry, not only because 10 players have withdrawn from the friendly in Bucharest, but because of the lack of contact to let him know what is going on.
He said: "I am sure the injuries are genuine but whether or not they are serious enough to miss an international, I am not sure.
"I want the managers to inform me so I can plan. I have lost 20 players for two back-to-back matches. I make concessions but I cannot keep doing that."
Hungary v Wales, Ferenc Puskas Stadium, tonight, 7.15pm
