Ole Gunnar Solskjaer's side were on an 11-game unbeaten run when football was suspended on March 13, a sequence that included nine wins.
“I'm getting better and better every day," said Ighalo.
“I'm still working every day and we've been training together the past two weeks now, so it's getting close to the game.
“The sharpness is coming, the fitness is coming and everything is going well.
“It's been strange, you know, because you have to stay two metres apart to talk to your team-mates.
“Sometimes, you need to get close to give them some signs but now it's two metres and it's kind of strange.
“But this is what we have to do for us to be safe and for the game to go on. We're ready to do it and we're happy to do it."
He added: “Everyone is training normally and training full and all that, so the squad is full and everyone is ready, I think.
“I can't wait for the league to start again. I'm really looking forward to it.
“We did mention today there could be 15 or 16 games left before the season is finished.
“No matter who starts the game, we know everybody is going to take part in the games.
“So we have to be ready, physically and mentally, because everybody is going to get a chance. We're working hard and I believe we're going to do great."
