Slade led the Bluebirds to victory over previously undefeated Nottingham Forest in his first match in charge, with goals from Federico Macheda and Peter Whittingham netting inside five minutes to kill off the game in the first half.
A Britt Assombalonga strike put the Bluebirds on edge in second half injury time, but the Welsh side managed to hold on to the three points which saw them move into mid-table - just four points off of the play-off places.
Having endured a torrid start to the season under former head coach Ole Gunnar Solskjaer, Slade’s arrival from League One side Leyton Orient appears to have settled the playing squad, and the coach is adamant that anything is possible now they have recorded a ‘massive’ victory over Forest - including promotion back into the Premier League.
Speaking to the Nottingham Post, Slade said: “This was a massive result for us. It was a scary last five minutes for us after Forest had scored, but we hung in there.
"I want to see all the players going beyond the call of duty. Anything is possible, including promotion, but it is all about building momentum and this is a great start.
"It is a good start, it is a solid start. That is all it is at this moment in time, of course. There were some pleasing things and there were some things that we still need to work on.
"But to get a result against a team that had been undefeated in the Championship so far is very pleasing. We want to gain some momentum and move up that table as quickly as we can.”
The head coach was a surprising appointment at the Cardiff City Stadium, having never managed above League One before. However, spells with Notts County and Leyton Orient established his name as one of the most promising coaches in the Football League, and he revealed that the Magpies owner called him to congratulate the victory over their city rivals.
"The owner called me after the game and he was pleased. I have had to wait a long time for this but it was worth it,” he added.
"It is a great opportunity for me, there is no denying that. But I am going to embrace it. I am going to enjoy the challenge, I am going to work exceptionally hard and I will try to pull everything together."
