Forest ended a turbulent week in which the chief executive and chief scout left the club by showing character to hold Derby to a 1-1 draw but McLeish is still hoping to reinforce his squad before the transfer window closes.
"I am going to try and be as busy as I can," he said. "I spoke to the owners after the game and they are very keen for us to add players to the squad.
"I think these guys have got a good chance of climbing further up the table but I would like to have an even better chance by adding new players. If we are going to be in amongst the challengers for the big prize, we need to score more goals.
"It was a great show of character from the players, the commitment they showed right to the final whistle was terrific. Hopefully they are starting to believe in themselves a bit more.
"Bouncing back from that rotten FA Cup performance against Oldham by beating Peterborough last week shows that 'bouncebackability'. Those kind of traits and characteristics allow them to believe in themselves."
Derby manager Nigel Clough was delighted to have striker Jamie Ward back in the starting line-up after a hamstring injury kept the Northern Ireland international out since the end of September.
He said: "That's his first start for three months and he's been our major goal threat when he's started this season so to not have the partnership we wanted out there for three months has been hard for us.
"He was not as sharp as he normally is but he got a great goal. He's one of those players, he's a little so and so a times on the pitch which is what we miss as well because we are nice lads on the pitch, too nice sometimes!
"They are lovely lads, Jeff (Hendrick) and Will (Hughes) but we want to see them having an edge to them as well but that will come."
