Bristol City's search for a striker looks set to go down to the wire.
The Robins have been linked to numerous attackers throughout the window, but have failed to land one so far.
Most recently, Eddie Nketiah has turned down City to go to Leeds United on loan from Arsenal, and Bobby Reid is unlikely to return to Ashton Gate, either.
The likes of Charlie Austin and Nahki Wells have been linked today, but with the window shut at 5pm, time is running out.
However, there is a way for the Robins to extend the window by two hours thanks to something called a deal sheet - here is how it works.
What is a deal sheet?
A deal sheet works as a way to extend the deadline slightly in order to finalise paperwork on a transfer that has been agreed by two clubs.
It can sometimes take a while to finalise the minutiae of transfers, so the added time is a way to make sure everything can be properly sorted.
What is on a deal sheet?
A deal sheet can only be valid if the two teams involved in a deal are named on it, alongside the player being transferred and a brief breakdown of the finances involved.
It means that, basically, to get an extension, a deal must have already been agreed with a club for a particular player.
What is the deadline for a deal sheet?
Deal sheets must be sent to the FA before the 5pm transfer deadline to be valid, and are only issued in the last two hours before the transfer window to be used as a last resort for teams running out of time to complete the paperwork involved in a transfer.
How much extra time does a deal sheet give you?
It buys clubs two extra hours to complete all of the paperwork and register a player.
If a club cannot file the paperwork by 7pm, it means they have to wait until the next transfer window, as famously happened to Leicester City when they were 14 seconds late to submit paperwork for Adrien Silver in 2017.
