Ho told the Echo that his old pal Cameron Jerome was affected by the Ninian Park crowd
'They upset Cameron when he came back here,' said Langley.
'He rang me after the game and was upset about the reaction. Cams could not understand why they booed him and nor can I.
'He deserved better then that.
'Here was a player who in his second season became the highest scorer at the club, cost them nothing and was sold for £4m, a 100 per cent profit. And it was the club that sold him, he did not ask to go!'
Langley says he knows what to expect and it won't affect him.
'I know it's coming and it's no big deal to me. When I come to Cardiff to see friends City fans are very pleasant to me and there are no problems. But once they go through those gates they change and it all kicks off.'
Langley missed a penalty in midweek when Luton drew at home to Colchester. He won the penalty after being fouled but put his effort against the crossbar.
