Manchester United boss Ole Gunnar Solskjaer admits they may end the winter market with no new additions on Friday.
With four days left before the transfer deadline, United are no nearer to signing any players, with no agreement with Sporting Lisbon on a fee for Bruno Fernandes.
“We've got players here we're working hard to get back as well," said Solskajer.
“I can't remember how many good ones we've brought in and good deals in January.
“Henrik Larsson was good, Nemanja Vidic and Patrice Evra.
“It's very hard, the clubs don't want to lose their best players and Alexis [Sanchez] will come back in the summer and prove you all wrong."
