Some young players lack the social skills to communicate well, according to League OneBarnsley boss Lee Johnson. Former Oldham boss Johnson, who took over at Oakwell in March, has a squad with an average age of just under 23.
He told BBC Radio Sheffield: "It's a real problem, not just in football but society, people seem to lack the social skills to express themselves.
"That's why the Championship is full of 27 to 32-year-olds who can dig somebody out to get the best from them."
He added: "You can improve people technically and you can motivate for a short period of time but generally people will revert to their natural personality."
