He said: "I am very confident that in time we will get it right in this division.
"I have said that our season will not really start until the transfer window ends, now it is over and we have got players in.
"The result disappointed me. To show such a lack of discipline and care is very disappointing. We made silly mistakes and some of my players are not brave enough.
"That cost us dearly, one or two of them are freezing at this level, at this level they are showing themselves not to be brave enough.
"They are standing and admiring top-class players and letting them play."
He added: "All we can do is our best in games against teams like Liverpool. I will not criticise any one player, we are in this together.
"But it is good we are not playing for two weeks. We can get players fit and get new players who have arrived bedded in. Kenny Miller has arrived, he has a hamstring injury and now we can get him fit.
"He is a confident lad, a bit arrogant and he will be a threat up front for us."
