Macheda never had a chance to record a hat-trick on his home debut after being substituted 20 minutes from time but Dickov said after the 2-2 home draw with Nottingham Forest: "He's not had a lot of games recently and we had to bring him off.
"But the boy is going to be a top player. He came here when he had a chance to join bigger clubs because he just wants to play football.
"He's been unlucky with some of the clubs he's been at on loan. I think one of them lost their manager soon after he arrived so I'm just happy to still be here."
Dickov added: "Joking apart I think he will maybe take three or four games to settle in before we see the best of him.
"There's a lot more to come from him - I'm certain of that."
Macheda fired Rovers in front after latching onto a pass from Theo Robinson in the 35th minute and restored the lead with a superbly-crafted goal in the 52nd minute after Chris Cohen had equalised.
Cohen scored with a powerful shot in the 40th minute and it needed another spectacular strike from Andy Reid to snatch a point nine minutes from time.
Dickov added: "We're possibly a little bit disappointed not to have three points after twice being in front but first and foremost it was a fantastic game of football between two teams that really wanted to win.
" I changed the side around because we wanted to be brave and bold and really go for it by playing three strikers.
"Some of the football we played against a top team that will be up there at the end of the season was magnificent and it shows we can be competitive and get better in this league."
Forest boss Billy Davies said: "We might have gone on to win the game after grabbing the second goal but a point's a point away from home and there are no easy games in this league.
"I thought we controlled the ball but lacked a cutting edge.
"Our play in the final third was a bit disappointing although we did well in the first half and they scored against the run of play.
"When it comes to the second half we have to learn not to shoot ourselves in the foot because it was our careless play that led to the second goal"
He added: "We are a work in progress and I'm delighted where we are at present.
"If I had to pick one of the goals we scored today as the best it would have to be Cohen's because he's been inspirational.
"But that's not taking anything away from Reid's goal because that was simply sensational.
" We were a little bit slack at times but we never give in and that's the character these players have".
