It means he is concerned at the way you go about things, and not punishing players enough for their misbehaviour. For example, if they were sent off, and it was a their second or third time, and you warn them, that's basically a slap on the wrist.
You need to be more demanding at home, saying "You can win tonight" or "I expect a win" against smaller teams, and criticise them if they draw or lose at home, with disappointment - even anger if they played very poorly.
EDIT:
Also, use correct grammer please.
