"Hopefully something can be done in the next few days," said Celtic boss Neil Lennon, adding: "Hopefully he brings us some creativity, goals as well. I think he would be good in the dressing room, as well."
However, Everton and Wolves remain in the hunt, with Moyes confirming yesterday his club are making a late attempt to lure McFadden back to Goodison.
"We have been talking to James and his people," he said.
