Jovetic joined City last summer from Fiorentina, but injury has restricted the Montenegro international to just one Premier League start.
He has not featured since the end of October, and there have been reports that the 24-year-old is suffering from homesickness.
The forward is closing on a return to first-team action and Richards is aware Jovetic will have a battle on his hands due to the form of Sergio Aguero, Alvaro Negredo and Edin Dzeko.
Richards said: "It's going to be hard for him to get into this team, but I'm sure he will be working hard and doing everything he can.
"I've trained with him. I think if you saw him in the AC Milan game pre-season, I know it was only pre-season, but it was against good opposition and he ripped them to shreds with his movement, skill and touch.
"But I think the strikers have got everything. Sergio has pace and power. Edin is a good finisher and good in the air. Negredo runs around like a man possessed and is a great finisher. Jovetic has skill and technique.
"They've all got something, some sort of gift to bring to the team and it just seems to be clicking at the moment. If we want to win the league, if we want to win trophies, they are going to be key.
"Last season it was more about defenders doing well. I think this season it is more about the attackers and that's why we look so good."
