Macheda admits he's eager for a run of first team games at his new club.
The Italy Under-21 striker told Gazzetta dello Sport: "There are still a couple of faxes (to be sent) but sometime between Wednesday and Thursday I will be in Italy. Genoa is a beautiful city and I am happy.
"I am only playing 10-20 minute spells in games currently and that is not helping my growth.
Ferguson is of the same opinion.
"In this regard, we are all happy because in six months' time, Manchester United will get a stronger player."
But the Rome-born youngster was keen to stress he should not be viewed as a direct replacement for the former Real Madrid star.
"Cassano is a champion while it's the first time I will have played in Serie A," he said. "Cassano and I are players with very different characteristics and on two different levels.
"I know there is a lot of expectation on me but the responsibility does not scare me. If I don't play I won't mature.
"Here the football is very tactical but I have no fear."
