Asked to rate his own and the team's performance out of 10, he said: "It'll be a five, might even nick a six if we win Saturday."
Despite some fan discontent, Slade is adamant he is the man to take Cardiff into next season. "I believe in myself," he added.
"And I think there is a growing unity in the changing room.
"It's a strong squad together, a nucleus of a strong squad which needs to be strengthened. We are trying to do that as a group despite the criticism.
"It happens, this is football. It's not always going to be rosy. You have flack from time to time at every football club."
Though a top six place was the aim when he arrived, he said there were a lot of issues to address and he felt it was too early for fans to judge him.
"They should decide over a period, I don't think it is the right time.
"Once we have a pre-season under our belts, had a summer and we have regrouped, then may be that is the time to have a look whether significant progress has been made."
