Shola Ameobi and Andy Carroll continue to interest Norwich, but could Clark try and take them to Huddersfield.
Clark, preparing for his fourth match in charge, has stressed he will only bring a better quality of player to the club.
Will Clark Come 'Raiding' For Terriers?
Clark (talking to the Huddersfield Examiner): "We talk every day, and pretty much every hour, about possible targets, whether it be this month or in the close-season.
"If something pops up that we think might benefit us, then we will try to do it, but we won't sign players for the sake of it.
"I've gone on record as saying I'm delighted with the players I have inherited. The lads who are already here have been doing absolutely everything we have asked of them, both in training and matches.
"We've had two wins out of three, and while we were all disappointed about the defeat at Carlisle, there was no questioning the commitment and desire."
Clark's old pal Andy Cole has backed him to be a big hit as a manager.
And the former United No 9 has not ruled out that the pair may be reunited in a coaching capacity.
Clark has Terry McDermott, Steve Black and Derek Fazakerley already behind him.
Cole: "It didn't surprise to see Clarky going into management one little bit.
"He worked with youth teams even when I played at Newcastle.
"He is passionate about the game and when he was coach at Norwich he was trying to get me to play for them!
"I spoke to him soon after he got the job at Huddersfield, and it's good he has surrounded himself with his own staff he knows and trusts.
"I genuinely believe he will do well there, and it's because of him that I might get a coaching job in the future on the back of it, because he is from my generation.
"If you look at the crowds they are getting now, 14,000 it is a good sign - and they could be massive.
"It would be great to see them get in the Championship under Clarky.
"I'm looking to do coaching badges in May. But for now I am enjoying my retirement.
"The media work is also something I enjoy, but I can't rule out anything in the future."
