Sheffield Wednesday have been left frustrated after seeing a move for Queens Park Rangers winger Lee Cook break down.
The Owls saw an offer accepted by Rangers, with an agreement reached on a loan deal with a view to a permanent transfer being pushed through in the summer.
Both clubs were hoping the switch would be completed before 11pm on Monday, when the January transfer window slammed shut.
A move failed to materialise, though, as Cook, who is still hoping to force his way into Neil Warnock's plans at Loftus Road, pulled the plug.
Disappointed Owls chairman Milan Mandaric told The Star: "Everything was done between the clubs and the deal was ready to be closed.
"We negotiated very hard but then the player pulled out.
"We're disappointed, all of us, myself, Paul Aldridge [vice-chairman] and Alan [Irvine] but we're not giving up."
Despite missing out on Cook, Wednesday were able to add five fresh faces to their ranks during the winter window.
Reda Johnson, Michael Morrison, Mark Reynolds, Gary Madine and Isaiah Osbourne have all been snapped up on various long and short-term deals, and Mandaric has hinted that there may be more new arrivals to come.
"There will be opportunities for us in the near future under the loan system," he said.
"We're not giving up on that one [the Cook issue] and there are another two or three players that we shall be looking at in the next few days, on a loan basis."
