Manchester United boss Erik ten Hag says he wants them to work the winter market to the final minute this week.
With the window to close on January 31, Ten Hag insists they must keep pushing to improve his squad.
The manager said, "In the coming days, if we had the opportunity I would go for it but that's not also up to me, that's also clear.
"I think this club always has to have the approach that every day you have to get better so if there are opportunities to get better then you have to strike.
"That's my approach so I'm looking around, to research but I have an idea with which profiles we could strengthen the squad."
