Former England U21 boss Stuart Pearce has taken aim at Manchester United defender Phil Jones and Arsenal attacker Alex Oxlade-Chamberlain.
Both players snubbed this summer's U21 Euros.
Psycho said: "There were eight players with senior international caps who could have played for my Under-21s.
"Apathy played a big part of it - the Oxlade-Chamberlains of this world, the Phil Joneses, because they didn't want to come.
"Once they go through the golden ivory towers of the seniors they don't want to come and play with the Under-21s any more. Until we solve that problem there will be no success."
