Macheda joined Rovers on a month-long loan in mid-September but a hamstring injury at the beginning of October cut short his stay at the Sky Bet Championship club.
The 22-year-old Italian has been receiving treatment back at United and is edging nearer to a return to fitness, and Dickov plans to contact the Old Trafford club to see if he can bring Macheda back.
Dickov is keen to add to his squad after the 4-0 Championship hammering by managerless Middesbrough and he said: "Kiko is getting closer to being fit again and although I have not spoken to United for a few weeks, I will be on the phone soon to see if we can get him back here as he was a big plus to the side with his eye for goal.
"I am always looking at how I can strengthen the side and this week I have been away a few days looking at players. If I see again what I saw on Friday night, I will look to bring in other players to play instead.
"I'm looking at players I can bring in up to January and to be honest Friday night changed my mind a little bit. I don't think I will be bringing in anyone before Saturday at this moment in time.
"These lads that are here know that if they go out and do the right things that I expect, I will back them all the way but on Friday I saw none of the collective basics I know they can do.
"I have my own ideas what went wrong and we have worked on the lads this week, so they have Saturday to prove to me we can be a collective group who put the team first not a group of individuals. If it does not change I will look at whom I can bring in."
