Former Hoops' striker Miller is set to resume his 33-goal partnership with Kris Boyd after both players returned from injury after the goalless draw against St Mirren in the Active Nations Scottish Cup tie on Saturday.
Parkhead boss Tony Mowbray has yet to identify his preferred strike force after bringing in Robbie Keane, Morten Rasmussen, Diomansy Kamara in the January transfer window to augment the presence of Marc-Antoine Fortune and Georgios Samaras.
Miller claimed that the Light Blues' squad contained "enough firepower to go and win this league," but ahead of the visit of Hearts, Loovens, encouraged by the fact that all three new boys scored in the 4-2 cup win against Dunfermline at East End Park, had his say.
"I don't really agree with that," he said.
"We have some great strikers,
"If you have seen our recent games then you will have seen the chances we have created.
"It's just for us to wait for that one game where it all clicks and they will all go in.
"There are still 15 or 16 games so there are plenty of points to play for.
"We have to play Rangers twice so we will see.
"But we need to make sure we get a run going and don't drop any more points."
Rasmussen has already notched twice since his move from Brondby and while Loovens would not compare the Danish international with Boyd, he believes Tony Mowbray has added the last piece to his forward's jigsaw.
"I don't want to compare him with anyone," the former Cardiff stopper said.
"All he needs is to score goals and so far he has done that.
"Rasmussen is a different type of player, he is a big strong guy, who has a nose for goals.
"He is always in the penalty box where you need to be to score goals.
"We don't score many scrappy goals but we scored one on Sunday (at Dunfermline).
"He has a feeling for that and it is a quality that we have lacked."
Mowbray is relaxed about the prospect of the 10-point gap remaining by the time the Old Firm meet again at the end of February.
"It's not a concern at all," he said.
"We could win every game up to then and the lead might not be cut.
"We have just got to try and win our football matches.
"We can't affect what other teams do until we play them so at this moment we have to look after ourselves and try to get the points."
