Ronnie Moore wants to bring in a striker to aid Tranmere's promotion push before Thursday's transfer deadline.
Top scorer Jake Cassidy returned to Wolves at the end of his loan spell earlier this month and, while Moore remains in contact with the Wales Under-21 frontman's parent club, he is exploring other avenues to bring in a physical presence up front.
One such target was Millwall youngster John Marquis, although the 20-year-old's FA Cup winner against Aston Villa on Friday night makes a move to Prenton Park unlikely in Moore's eyes.
The Rovers boss told his club's official website: "It's got to be a Cole Stockton type, the bigger lad. If you look at what we've got now with Michael O'Halloran, David Amoo and Jean-Louis Akpa Akpro, they're all players who can play on the shoulder. We've only got young Cole who has got a bit of meat on him.
"We were unfortunate as John Marquis, who scored for Millwall at the weekend, nearly came to us a month ago. It looked like things were going to happen for us but they didn't and he came on and scored the winner against Villa the other day.
"We speak to Wolves weekly and they're just monitoring the situation. How long do we wait? There's not that many Jake Cassidys about, if there were we'd have had to do something without waiting for Jake. I'll speak to them again and see if the situation has changed."
Donervorn Daniels and O'Halloran see their loan stays expire in the coming days and, although Moore is intent on keeping West Brom defender Daniels, the wide attacking options offered by Joe Thompson and fit-again Abdulai Bell-Baggie mean the latter may end up back with Bolton.
"Donervorn and Michael are up soon," Moore added. "We'll have a chat with them and see what road we're going to go down. Certainly with Don we need a centre-back as that's where we're short.
"With Michael we have to have a look at things because Bell-Baggie is fit now and we've got Thompson who can play wide too."
