Berbatov, who finished joint top scorer in the Premier League last season, has so far this season just come on as a substitute against West Brom.
“It is hard because of the number of strikers we have,” said Ferguson.
“Michael Owen is there, Federico Macheda, Mame Biram Diouf. Danny Welbeck won’t be back next week but probably the week after. It is not easy.
“Dimitar has been training terrific. His attitude is spot on. He will get his game time as the season wears on. There is no question about that.”
